Uncle Doug, one of my first amp builds was a Fender Champ style amp build fitted inside a 1936 Philco radio art deco cabinet, I found in the attic of my mother-in-laws house on Lake geneva, WI.

As an added comment, I use my Stihl (Al Gore approved) gas leaf blower to clean out my table saw, router table and sander in the backyard. Works like a champ. It is even better for cleaning out my Ford F-150 interior. I start her up, open the windows, turn on the air (high) and blast the interior. Way easier than vacumming.

Hello again Uncle Doug, Rusty and Jack. It seems I never get enough of your detailed videos (as always) of the way things should be done, not the way they may be done. A new blade is important, as cutting some wood products (especially that grained particle board) causes sparks to come out when sawing against the carbide teeth of the 10 inch table saw blades. Wears out the sharpness of the carbide teeth very quickly. I see you got the the traditional 3/4 inch good grained pine. That's good as it is important for cabinet resonance and many amp manufacturers use pine because of that. I have a 40 year old sabre saw, that has those blades that can bite you, but for cutting out some funny shapes or metal it still has it uses. I have pretty much have all the woodworking tools/saws/bandsaws and a myriad of clamps of different shapes and sizes. I see that Jack your cat, only gets into the action when he wants some attention. As you know, cats don't do woodwork or any other kind of work for that matter. LOL! Nice work on the wood cabinet especially with those all important box finger joints. The bull nosed edges of the cabinet make it very attractive looking. Those step bits take a powerful drill press to drive it. Very nice transformer layout. Go to to see the use of rubber grommets, not every commercial amp uses these. Solid looking 16 guage chassis..how much do you estimate it weighs without any components added yet. Looks very heavy to me.

+SuperCarver2011 Thanks so much for your detailed and favorable analysis, SC. I would guess that the chassis weighs around 4 lbs. I was somewhat apprehensive about the difficulty of machining it, but everything went quite well. I tried to stress the importance of proper lubrication to expedite the drilling process and preserve the drill bits. I fear that many people simply try to force the bit through the metal with no lubrication at all.....not a good idea.

@SuperCarver2011

8 жыл бұрын

+Uncle Doug Yes, I have broken many small bits by forcing the bits through metal on a drill press (especially aluminum) causing the bit to bind up and twist off, leaving me having to buy another one to finish the job. Same situation with hacksaw blades when you just go at it without some lubrication on the metal blade

Really enjoying this series Doug and the quality of the build throughout. The finger jointing is a great way of jointing, i more often than not see butt joints and screws and strengthened with blocks even in commercial project. Thanks for showing us how to do it the right way. Take care and all the best to Rusty and Jack. Colin

Uncle Doug, this video/documenting is really quite a fine service.

Thanks so much, Brad. Nice comments like yours make it all worthwhile :) Yes, indeed, loving animals comes with a price..... but generally the rewards outweigh the final cost.

What you might want to consider is what I did for the Magnaclone: get a scrap piece of wood and use wood screws to mount the terminal strips to it (lay out the terminal strips with the same measurements they'll be in the chassis.) This lets you wire up almost everything, without having to work inside the chassis. Once you've got the terminal strips wired up, you can transfer them to the chassis, screw them in (or rivet, in your case), and then just run wires to the tube sockets, pots and transformers. I got my terminal strips laid out in the chassis the same way you did, then drilled their mounting holes. Then I stuck a board under the chassis and marked through the holes with a Sharpie. Then I just used some short wood screws to hold the terminal strips to the board while I soldered the components on.

Hi Uncle Doug! Maan that timber cabinet looks like it was made by a cabinetmaker in a woodshop! Very professional looking! Those finger-jointed corners look magnificent mate! Flawless & strong as all get out! Great idea bolting the speaker centre-hole & using your router to cut it! Unfortunately, I didn't have a router table to make the 15 inch cutout in the baffle for my 'Silicon Chip' magazine Majestic speakers that I built. I just had to use a jigsaw, unfortunately. After I cut out the hole (which was naturally quite rough!), I smeared a small amount of black boot polish around the edge of the timber disk that I had cut out & screwed a 4 inch length of 1 x 1 inch cleat into the disk centre hole as a handle. Then I rotated the disk inside the hole to mark the high points in the speaker cut-out, then sanded the high points down with sandpaper wrapped around a piece of dowel. I repeated this process until there were no high points left. The process worked really well, & I glued up & painted the internal edges of the speaker cut-out with wood glue & primer. I managed to source some real nice 10-32 T-nuts for each of the 8 blackened allan-key head mounting bolts, which I 'siliconed' & hammered in for a perfect airtight seal. The speakers are rated at 300W RMS @12.5Hz - 20kHz so I had to be sure there were no air leaks, & there were none! Yay! Your metal chassis looks fantastic mate, & I especially like your idea of an internal steel wall to keep power supply noises out of the preamp circuitry! I hope you kept your furry friends out of the workshop while you were drilling all the chassis holes, with all that razor sharp metal swarf getting flung about! I guess all the racket you must have made would have deterred them a bit ay? A totally wonderful, professional job mate, with just one possible problem. I was a bit worried when I saw that you used a rocker switch for the 6L6/6V6 selector, which may get accidentally bumped. I dunno, but I would have used a slide switch that fits behind the panel & requires a screwdriver to move it, like mains voltage selector switches that I have seen. Maybe it's not such a problem, but may run 6V6's too hot if in the 6L6 position? You've probably already thought of that scenario, but anyway that's the only worry I have for your amp my friend! Other than that, it's a 12/10!

Hey Doug, another great series. While I completely understand your choice of chassis material, I will point out of couple of things for followers who may not be familiar with hot-rolled sheet steel, which is what you used. That "blueing" is actually mill scale from the hot-rolling process and it's a lousy conducter (makes poor grounds but a GREAT capacitor, though). That stuff fiercely resists TIG welding unless you've scrupulously ground away the mill scale and cleaned the weld surfaces with alcohol or other appropriate cleaner. Additionally, if you live in a moist climate such as Middle Tennessee (Nashville) where gulf air is constantly streaming up this way, that steel is going to start rusting five minutes after you drill the first hole. Then, you're left with the option of painting (after grinding away the mill scale as paint won't stick to it) or throwing it away and selecting a more suitable chassis material. Please understand this is not a criticism of your choice of material. For just a few bucks, on the other hand, a metal distributor will sell you aluminum (or steel) "drops" for a fraction of the price of a sheet. An excellent choice might be a 5052 alum, for example, in .040 thickness. Easy to bend, MUCH easier on those expensive step drills, etc. And lastly, speaking of drilling, oil products never make good coolant for drilling as they lube the material instead of cooling it, which is the last thing you want. It LOOKS like you're drilling when you're actually rubbing your way through it. The MOST effective, and least expensive cutting fluid that I've ever used for drilling is a 50/50 mixture of Pine-Sol and tap water. Just my $.02.

@UncleDoug

7 жыл бұрын

Wow, thanks for the very informative input, Bruce. I have used aluminum for chassis in the past and found it easy to work, but difficult to bend without getting stress cracks. Most of the steel I use does not have mill scale, and with our 6 to 8% humidity, rust is not a big issue.....but I fully understand that it's a real problem in many parts of the world. I have been using a special cutting and threading fluid, but will definitely try your Pine-Sol recipe. Again, thanks so much for sharing this info with us :)

@brucechumley9195

7 жыл бұрын

There are actually two reasons that stress cracks develop in aluminum during bending: 1) the heat treat of the material, e.g., T3, T4, or T6 doesn't lend itself to working and 2) your bend radius is too tight for the thickness. For small amp chassis of the size we're dealing with here, 2024, 3004, 5052, or 6061, CONDITION O (pron "oh") alloys in .032 thickness would be PLENTY strong enough and EASILY cut, drilled, and bent. Using the bending process you demonstrated here would work perfectly on a piece of 2024-0, .032 and be fully as strong as that safe you built from the HR piece of steel. Please forgive for the crack about the "safe" - that appeared at the doorstep of my tongue and I was powerless to keep it from just tumbling on out there. Best wishes.

Excellent again. Very good advice regarding the output transformer being off-axis from the power transformer! I didn't know that. Also, you aren't there yet, but reverb pan orientation is important. You don't want the output transducer/pickup of the reverb pan to be at the same end of the cab as the power transformer or it could pick up noise from the transformer.

@UncleDoug

+tremelo68 Thanks so much, Trem68. You're absolutely correct about the output transducer being as far as possible from the PT. Over the years, I have observed the hum that can occur if it isn't.

Really makes one appreciate just how labor-intensive it is to build an amp from design and construction, to finished product. I can`t imagine how one would put a price on the blood, sweat, and dog biscuits and still call it an affordable amp once its all said and done. I know its not an amp you intend to sell really, but more of a personal endeavor and a hobby for your own enjoyment. Lastly, and it shouldn't be a huge concern as I wouldn't think there are any nefarious characters lurking in our midst, however, you may want to blur out your license plate of your Jeep just to be sure. There is a tool in editing that provides that `blur-out faces` feature. I`m sure it would work for license plates just the same. All the best good sir, and looking forward to the final chapter in this series. Cheers!

Re the license plate, it was an oversight and probably can't be remedied once the video is posted. I guess if anyone wants to drive all the way down here to face Rusty's fangs, claymore mines, barbed wire, and five clips of .45 ACP to steal an old Jeep and some homemade amps, then there is just no stopping them :)) Thanks for your concern.

Thanks, Mario, and regards from both Rusty and me.....in the hinterlands of far west Texas.

use a drilling lubricant! Brilliant! Having just done this a few times DIY, it never would have occurred to me, but it makes perfect sense. I was a bit surprised that you used porcelain tube sockets. My preference is to use those dirt brown Belkins. I often will design my amp's faceplates on my laptop, and lay it out real nice and have that made before I drill the chassis. That way I can get it to conform to the faceplate perfectly. It helps that I have some background in graphic design.

+Alva Goldbook Yes, by all means use a proper lubricant, Alva.....and not WD40 or some silicon spray. I use a special machinist's lube that is specified for drilling and tapping. It makes the difference between a 3-second drilling time and a 3-minute (smoking, bit-destroying) drilling time. Your faceplate idea sounds great. I hope mine turns out nearly as well :)

+Uncle Doug I get my faceplates made for around $35 each. It ends up being pricey this way. One of these days I'll set up my own silk screening station, but this is how I do it for now. Here's the faceplate graphic I designed for that rebuild of my Fender Hot Rod Deville into a blackface type amp I was talking about earlier. The spacing of the holes are based upon the existing chassis. i.imgur.com/1PjRAZQ.png

thanks for the tip . as far as the carpet tape I found a better way regular masking tape and super glue . put the masking tape on the template and the workpiece then a thin bead of super glue holds much better . cost much less and is much thinner. I use that to make inserts for my saws . to cut out vents in back panels any number of things. thanks again

If the main filter capacitors at the power nodes are rated At 500 to 525 volts DC you could run a 5AR4 when running the 6L6 and then the 5Y3 when running the 6V6 even with the 2 position bias switch That way both the 6V6and6L6 can have two power settings each.

It was like I was looking over your shoulder! Are you going to make or order the dash/faceplate? Man that is a great idea to install terminal strips. It will cut back a little on over all weight and be so easy to wire to. Brilliant! Your production crew seems a little bored. I guess they can't wait to smell the completed amp. Thankz

+Audio Tech Labs You're welcome, ATL. I will make my own nameplate, as described in one of my videos. Glad you like the terminal strips. Usually, two parallel rows, almost full length, will do the job. I may have to add a couple as the wiring progresses.

If I was a manufacturer, I'd approach you for your prototype... but my question was, did you consider plating the chassis? ...and though I know the cab will be really boss (or 'dope' or 'bomb' as the youngsters say nowadays) with the covering, I can't help but wonder how she would've looked with a natural or a sunburst finish... But no matter as I know it'll be smokin' in the end (;-b) Oh and also, I'm so glad you hinted at the possibility of using a 6L6 or a 7027 or 6550 for those times when a bit more power might be desirable... Really enjoying this series. thanx and... cheers

Excellent Uncle Doug !! While watching and listening to you handle the 16 GA chassis - it sounded so very solid - I was wondering how much it weighed !! I noted your earlier comment that perhaps 18 GA would have been adequate. Any conjecture as to how much lighter that would be ? Thanks for all the great videos !!!

We're all enjoying this build immensely! Doug, what gauge is the sheet metal of your chassis? I'm making a new front panel for my variac and I'm wondering what gauge metal those step bits will go thru. I'm pretty sure what I currently have is 15 ga. Needs to be fairly heavy to hold the variac mechanism. Thanks again for the great videos!!

+Uncle Doug and Rusty.....I own three (3) Fender FSR Acoustasonic 150's...Solid Mahogany amps.....Fender only made "300" of these "Factory Special Run" amps. Bought in 2008 down turn when they couldn't be given away...now... they can't be had. Beautiful dark brown Mahogany w/ clear Hi-gloss poly finish...finger jointed....super dense solid Mahogany wood. They all weigh a bloody ton. They are solid-state !!!!....but the most beautiful perfect and versatile amp Fender ever made. Designed for acoustic...it's stereo....but has a channel set up for electric w/ Blackface...Tweed...British......set-ups ....Heck it even has a low Z mic input with phantom power...you could run a ribbon mic with it.....Direct out.....best amps I've ever owned.....from a violin...to a flute.. to a cello... to a Martin ....to a Tele.. Buying 3 means i bought .....one (1) percent ....of Fender's entire inventory......Hah! (The only Amp ever made that your Wife would allow in the living room.....Hah!) Mahogany should be your next build.......or maybe Cherry....Walnut would be nice...(Should be a hard wood that's why Marshall used birch ply instead of pine ply on their cabs ...density! ) Three coats of Poly...... They're Heavy & and most Beautiful...(the dense wood changes the tone for the better)...B.

Perhaps, if you have proper bending tools, Nathan, but I've found that if you drill before hand-bending, the metal around the holes may deform.

+HungryFreaksDaddy You're welcome, HF. As far as I know, it's just to prevent chafing and possible short circuits. Lots of amps don't have them.....but to be honest, they probably should. I always feel safer with them. If you don't have them, you could wind some electrical tape around the wires where they pass through the chassis wall.

I was wondering how you’d upholster the cutaway for the controls.I’m sure you’ve noticed that Fender and vox have an upside down“V” cut with a strip under it in the corners. I wonder why they don’t just do the controls the same way as the oval cuts on the back of amps.

@UncleDoug

It has to do with the radius of the curve and the thickness of the wood being covered, William. The rear panels are much thinner than the top panel and the covering material can be stretched without cutting.

@@UncleDoug Thanx UD. Makes sense. I was wondering how I was gonna approach that if I make a control cut out. I’ll keep thickness in mind.

how well did cutting out the hole for the speaker work when you routed the last bit of it . I am very interested. I build cabinets every day I have tried several ways and have thought about doing it like that but figured at the very last inch it would cause problems . I use templates I originally made by bolting a speaker to ply and using a flush trim bit the bearing riding on the speaker basket or more correctly the foam or cardboard gasket. but from many uses the templates wear out mostly from putting the studs through them

+Jim Lundin Make a template out of 3/4 inch plywood. Spray it with several coats of polyurethane. Use double stick carpet tape to hold it in place while you cut with a template router bit. ( bearing on top) if you don't spray the template the tape will peal the wood out in chunks after lots of use.

+Jim Lundin It worked perfectly, Jim, all the way around. I too was worried that once the center circle was freed from the baffle, the baffle might wander and get chewed up.....but there was no problem at all.

What step bit did you use? Can you use the same bit for both Octal and B9A valve sockets?
