I love watchin Shango clinko turnculate old stereos and TV's

My 84 YO aunt has a very similar looking Magnavox but with a B/W TV included. I believe it (the TV) has one of those tuning fork remotes too. I remember some cousins connected up a early video game to it in the mid 1980s one holiday gathering. TV worked but was not very bright. Has a fairly rounded screen as I recall. Aunt mentioned to me probably 10yrs ago that the record player had quit and she could not play xmas records on it anymore. It was still in her house the last time I was there in 2021. I've always suspected she got it 2nd hand someplace. My earliest memories of it are from the mid 1970s.

MY GRAND PARENTS HAD ONE IN MID 60S. IT WAS STILL WORKING 40 PLUS YEARS LATER. GREAT FORT WAYNE, IN STEREO.

Thankful you make these videos, I can only imagine the trouble but the work you go through to bring us this content, it is appreciated. Some of these old beasts must be frustrating, but it's a pleasure to watch your work.

This was good enough to watch the whole way through. I picked one of these up in working order 10 years ago. It sounded great. Always wondered what the guts did. Finally got insight from this video. Thanks.

OK I sucked at TVs but I still do these consoles in my sleep blindfolded and can say that while you went more than a bit roundiebout you got it basically right and accomplished the task at hand. It was tons of fun to watch while I wasn't screaming at the screen.😋🤣 We in a production environment wouldn't waste any time on old caps but you know that with TVs. I just wish 2022 technology allowed me to demo you how we do FM now. It really is a jaw dropping experience to go from caps, coils, resistors and tubes/transistors to software defined radio with no parts at all but a pre-existing PC. and a cheap USB dongle. Also I didn't even know that rpm phone app existed. I've been on the strobe disc. I will use the app going forward. Thank you fine sir. You're a gentleman and a scholar. I did enjoy doing CRT setups back in the day but the business aspect and that 40KV thingie (60KV if you include the Zeniths with the neck blown off the bulb from the bad cap) kind of kept me from getting all pro with it.

You've earned a gold star and a can of DeOxit!

RCA developed stereophonic sound in around 1958 for phonographs. That's probably what that patent is referring to. These Magnavox consoles are great consoles. Very well built, as you pointed out. And they can really sound great when they are working correctly. By the end I was practically screaming at the screen for you to replace caps in that power chassis. Man, this thing could still be great. Get in there and knock those coupling caps out and fix that oscillation too.

As usual your videos are very entertaining. The best part of this unit is the amplifier and the speakers. If you work to pull out that amplifier and recap it you would have a very nice amp there. Back in the day these units sounded fantastic. About 35 years ago I was able to drag one home that was found in the street but it was much larger and had the television in it. The CRT was bad in the TV so actually all I did was parted it out the amp the turntable the speakers and the rest went in the trash.

That is actually a very nice amplifier. David Gillespie posted a thread over on AudioKarma called "More Fun with Magnavox: The 9300 Series." He modifies that exact amplifier with minimal effort and effectively makes it "HiFi" (at least as HiFi as tubes can be.) I have one of those amps myself, and am currently building a second one from scratch. They sound very nice. That is an awesome find! NOT TRASH!

This is a premium model. The Imperial line was only sold through Magnavox franchised dealers. You couldn't get this in a department store where the regular line was sold.

All your videos are really enjoyable but this one in particular was really great fun to watch, put it on and thought i'd watch a little and go get a drink and come back and watch the rest but ended up sitting down and watching it all. I think even today if that were all in running order with proper crossovers and some decent music fed into it it would still blow people away, especially the younger kids who have never heard music played on anything larger than a phone speaker before. I'd guess it was a portable CD player hooked up (badly) to the aux.. I had something similar 25 years ago now.. doesn't seem that long! 10-12 watts per channel in PP maybe? Never did get to see the underside of the amp/psu, wonder what the other side of that tuner plug looked like.. probably a rats nest of wires..do you think its probably a cathode bypass capacitor shorted / bad plate resistor to the output tubes causing them to redplate? finally that MPX unit really well made.. I recognized your comment about tubes with FM stereo being unreliable.. seen a lot of philco stuff that seemed to go out of alignment just by breathing on the leads!

It works absolutely fantastic, the cabinet is very nice, I'm sure he never had a restoration on it, so I belive its all original, I checked all the tubes in it when I got it, they are all Zenith, except for 1. That one is a GE. in the 28 years I've used It, its needed nothing, it just always works!

Those amps when working are awsome !! 15 watts a channel anywho !! Good video's my man !!!

While I miss the CRT work, this unstraight troubleshooting by our unrestrained host was wonderful walk down memories lane. My parents owned the Maggie model above this edition.

It has FM tuning eye, VIVIVIVIbrasonic, center bass woofer 15", L R 8" mid-range, LR 1" tweeter, changer, etc. Here is the kicker: my brother kept it, original tubes, resistors, and caps. Except for the dirty pots, it operates perfectly...60 freaking years later. The problem is not with corporate WOKE which is just PR. The problem is that nothing is done for decades any more.

My understanding was that Zenith and somebody else, maybe GE or Maggotbox came out with systems that were so close to identical that the FCC authorized both and let broadcasters pick one as they both worked on all receivers. Anyway this mid side technique was used for many things including the CD4 Quadradisc and analog NTSC stereo (with DBX added to the L-R). There are even vestiges of it in the NTSC color broadcast specification. It was just how you did it in analog. Now I do analog FM stereo both RX and TX in Python.

"I can heat it over here, and move it over there, if I am fast enough...." Nice way to get a warm tube experience.

"It works, it only needs a tube and a new needle!" 😄 I actually saw this statement in a FB Marketplace Ad for an old stereo console, a while back.

"I'm not going to fix the multiplexer" And then he disassembles and "fixes" the multiplexer "I'm not going to align the multiplexer" And then he gets the alignment generator out "I'm not going to hook a dual trace scope up to align this thing" And then it cuts to a shot of a dual trace scope hooked up to it I love this channel

Thanks for another Saturday morning special @1:14:29 ⭐️ ⭐️⭐️

The FCC authorized FM stereo broadcasting about two years before this console came off the assembly line.

I recently put an order in with Electronic Goldmine out of Arizona, and as part of that order I included one of their gold-pak capacitor bulk box. It contained about 40 of that style capacitors in the box of around 1000 caps. I had never seen one like that before. It sure resupplied me with caps, I should sort and sell a few hundred of the electrolytic in 4.7 to 470 most brand name caps at various voltages as my bin is overflowing with many of them. Good outfit for their large capacitor surprise packages.

Those 6BQ5 tubes I believe are Magnavox branded Telefunken tubes. Quite valuable. If you have a matched set of four that are all good, you're in the hundreds of $ for the set of those. You nailed it that the amp is worth way more than the console as a whole.

@alanrogs3990

The amp isn't worth that much but, you're right, the tubes, if Telefunken, are worth at least $150-$200 for a quad used.

Magnavox and Stromberg Carlson were the console stereos of choice when I was a kid back in the 60's, brings back good memories.

2:06 Never seen one of those before. On this side of the pond our 45s always had the same size spindle hole as LPs; we fitted centre pieces to records which had been "punched out" for juke-boxes, or the (rare at the time, at least for me) imported records. Also it'd be nice to see a follow-up .. and see what cooked! Hope someone will take this on. I know I would if distance (and space) weren't an issue.

Another great video Shango keep them coming

I've got a very similar model. I had a heck of a time trying to find service information for it, the only thing I could find was a Sam's for the tuner. Turned out the power choke must have shorted a few turns and the plate voltages were around 300 instead of the 245, which was causing the 6BQ5s to red plate. Added a resistor (okay, a 40 watt light bulb) which brought it back down.

These have a cathode bias circuit. If you ran into red plating you may have a shorted or leaking bypass cap on the cathode circuit of the 6BQ5 tubes or a leaking coupling cap to the 6BQ5 tubes. I would be sure and check those out if you haven't already done that.

It caught on fire just after you played LIGHT MY FIRE the Amp has gone SENTIENT!!!!!

Excellent video! I have this exact model and have started restoring it, including full recap, and want to get back to revisiting it, as it still has some remaining problems including too much 60 Hz hum which might be shielding or grounding issues somewhere. Mine also has crossover cap issues where one side has some treble and the other side has none at all out of the horns. I had two multiplex adapters for it and one worked and the other is quiet. I wonder if that 4 MFD cap in the quiet one is bad like on this one! I had to stop working on mine when I had people wanting me to repair other radios for them.

Magnavox were the best console stereos back in the 60s. They had the best sound snd best bass. I would have loved to had this when it was new.

had one of these all the time growing up, with the TV in the middle and angled satellite speakers as well~ was so awesome could pile on 7 LPs and play table tennis~ bout the time I was born in 65 till 1980 when the roof leaked and everything was rotted...in winter....still Ken the Engineer (bout like chris too you) pulled it apart and continued to use this as the Ping-pong amplifier

Best Radio res episode learned alot so fun

The FM multiplex standard chosen by the FCC is actually a combination of the GE and Zenith systems which were very similar. The main advantage of these systems over the competing Crosby system was the preservation of the 67 kHz SCA subcarrier which was an additional source of revenue for the FM stations. The chosen GE-Zenith system actually degraded overall S/N ratio in stereo for this reason...

Mr Shango 066 You are best to watch all your videos Keep up the good work

I'm surprised you had so many issues with this one, Magnavox tube gear is pretty robust. I'll bet the smoke at the end was from leaking paper coupling caps. Those wafer tube sockets were garbage, and GE used a ton of them in their radios. In fact, there are certain models where GE used them with a 50C5 output---the heat from the tube would bake the socket so bad that it would crack and short between pins. And I had one break into 4 pieces and fall through the chassis when I tried to reinsert the tube in the socket

Very interesting to find out where the stereo multiplex started and came from.

I really liked how at the end you imagined what it could have been like listening to this thing for the first time in 1963. The audio experience was cutting edge indeed. Also, did they hear the news of Kennedy's assassination on it? How many psychedlic Beatles 45s were spun on that adapter in 1964? I saw a house probably built in the 1950s like the one i grew up in that was sold about 10 years ago, sealed up and tirn down for a mega center.

Thanks to this video I learned. Well let me just say, I just picked up a 1962 magnavox theatre (27 pict. tube)no uhf/ am/fm tuner/phono Model (1MP422M). But it has close to the same amp and tuner ( except my am/fm tuner has a spot to turn the tv off and on. speakers have the same horns pointing forward, big woofers pointingat the ends of cabinet, same as that one. But I found out it's tough to get the Sams photofact for Magnav. consoles. I called one guy selling them Steve, he said take out the tuner, and take close up picture of it, and give him a drawing with the tube location and names and he'll take a couple of days & try and come up with the Sams. I just got it, seeing how it was all tube I hoped, th model # wasn't given in the add just said $100 bucks come and bring a truck. The "sun", must have been hitting the back of the tv for years as the model #paper was very hard to read I corrected 1 letter I had off from another person selling a simular unit that the paper tag wasn't bleached out. He just had sereis 1 & I have sereis 3. But I've only had It for less than 3 days. I think the tubes that said 62 were correct. I think they, went solid state in 1963. My tubes (high hrs set) are caked with dust, So I haven't read amything yet. But I looked at that metal inpression stamp No. on the multiplex board it matches your Number, maybe just a part No. But I didn't know what board that was or what It did. Thks for that informative part , about the multiplex and what it's job is. And how the tuner has special plugs and everything just will plug in.The only way to talk the wife into me, getting this, ( being as big and heavy as it is) was that it's my christmas present for 2023, except she did let me get a tube tester and Beltron CRT Tester Restorer With Dandy-Dapter Universal Adapter CA-28 $140.00 plus $30 shipping. I know I paid way to much for that. I tried to cancel it when I found he was charging double the going rate.

A good resto for one who wanted a modest power all- tube reciever. Plenty of work left!

This is a transitional cabinet design. It was used for a few years, on both the later tube models, and the early Astro-Sonics. I have a tube version of this console, with a multiplex, I would love to go to a new home, here in New Mexico. My cabinet is in better shape, too.

I really like 👍 this lengthy resurrection (video). Those square speaker 🔊 magnets 🧲 are interesting 🧐. “Cracklepony Mastercharge”, for the crackling sounds. I think “IPod”, or whichever ya said, has become obsolete technology. I wouldn’t want to put Bluetooth and everything into this, anyway, because it’s destroying the originality of this set. Glad 😀 to know that this AM/FM radio/record player is tube type. I’ll guess 1963. Your friend, Jeff.

Nice. I love it. I remember the turntable. Long long time ago

We had a 1962 Motorola console, and there was a switch position for FM stereo, but you had to pay extra to have a decoder installed. My understanding, many years later, was that the first couple of years of FM stereo, the FCC did not dictate the codex standard for the United States. Can't wait for part 2 of this where you flip it over and we find out what burned. .

Really unfortunate that this stereo repair failed and the system died, it's such a beautiful cabinet that had tons of potential.....

when I was a kid my family had one of these. I remember playing some old 45's and my Dad had some 33's

almost looks semi french provincial cabinet. Nice chassis. I like it. getting harder find these old units intact any more . so many went to the dump now...

Those tweeter horns are fantastic. Some of the early ones were Electro-Voice. Those might be EV's. Mine had solid black metal magnet caps.

It’s 1ST659A, with magnavox the chassis numbers rubber stamped on the tuner, amplifier, multiplex adapter, and tuner are how you find the Sam’s for them.

Shango its amazing to think that these old radiograms only output about 3.5watts a channel yet were very loud, their speakers although were paper cones were very efficient over 110db/w some of them, today its the other way around we have stupidly overpowered amplifiers with crap speakers about 86db/w efficiency, unfortunately paper cone drivers arent really any good for high power amps as they have the "oilcan" effect when turned up loud, basically the paper collapses like pushing in a coke can. you need aluminium drivers for high power and lots of bass.

I hope you find a home for that stereo for sure.

You had the wires carrying the audio into the amp laying right on that output tube that was oscillating. Maybe the high voltage swing from the plate was capacitively coupling back into the input wires causing the oscillation. Could be nothing wrong with the amp itself but just the wires need to be repositioned.

To me your videos are priceless.

I would love to know the exact source of the "this is only a test" transmitter. Seems to me like it's one of those roadside "emergency traffic alert" translators or similar.

It's funny whenever you have the signal generator going the KZread Auto subtitles say (applause).

These can have excellent sound quality when working right.

Love that FM multiplex module

Everybodys favorite station fits perfectly lol

A 60 year old radio without cigarette jam and rat piss? List this sucker as rare on EBay. 😂

We had a tube Packard Bell growing up. It was loud and very clean sounding. I wish I had one now. My McIntosh MAY sound better, but it had personality.

On a push-pull output circuit with a cathode bias design and you remove one of the output tubes you change the bias on the other tube so that it has to run way too hot which is why the tube was turning red.

This unit is very expensive unit in 1963! My parents tried to buy it used and it cost close to $400.00! I saw similar unit sold in furniture store in Philadelphia for $500.00 cash and with installment payment weekly payment plan with down payment with 23% interests rate, the payment still over than $8.00 per week back in 1972. The new car payment was $100.00 a month and full coverage insurance that about $650.00 per year for clean record driver.
