You won't find another guitar based KZreadr who shows how to diagnose problems and repair gear like Phil , the best part is that he explains things so clearly . You're a champion Phil and a gentleman too.

Jacob Reichert I did. However, I do not really fancy his attitude and style so much, so I do not follow him anymore, although I do not doubt his expertise in any way.

Yup you can really tell when someone has experience and he’s willing to share it in plain and simple terms so you understand what’s going on
Most musicians/techs like to keep everything a secret and you never hide anything from us. You’re a gem Phil.
Given that my mum actually made tubes at one point, and that she "tuned" our old black-and-white TV with a wooden spoon, I am happy to see this trick being passed on.

My Mum tuned my rebelious teen brain with wooden spoon...till it broke.
I know this is a pretty old vid but sure was helpful today, found 2 of my EL 84s bad using this method. One had the clanky glassy sound and the other one actually sparked inside and had a loud noise through the speaker, been chasing that one a few months thinking it was a loose wire to the speaker. Thank you Phillip , another great tip.
I love videos like this, thank you for your content. I may not come across this problem for 20 years, but this knowledge will stick in my brain!
Once again simple and very effective way of letting the community know how to detect an AMP issue and fix it! Gracias!!!
Definitely a review. Thanks for showing how to diagnose and change a bad tube. Looking forward to the next video!! Thanks Philip!!
Great to see that the techniques I learned in a television workshop over 50 years ago are still useful in this high tech age. I still have the very small plastic handled screwdriver (came from Woolworth's) that I always used.
This video was super helpful for me, when my tube preamp was generating loads of noise (and was super silent before) in the high gain distortion challen. Tapping against the tubes with a wooden pencil immediately showed me the microphonic tube. I replaced it with a new one and the problem was solved. Thanks so much for your practical videos! 🙂
I am currently hearing this noise from my amp. Now I know where to start. Thanks Philip!!!
The "Chopstick Diagnostic Test" worked for me. I dusted off my old "Silvertone 1482" and after having replaced the original damaged speaker with a new "Electro-Harmonex 12VR" , I thought that I was ready to create some tunes. With the amp warmed up, it started making a scratchy" noise kind of like an old FM radio static that you get when the tuner is between the stations! I found your video and used your method and found the noise making culprits to be two 12AX7 tubes. I carefully cleaned the tube tips with a needle file, sprayed the sockets with electronics cleaner, carefully replaced the tubes, and at this time the noise is gone and the amp is sounding great! Thank you Phil for spending your time making these helpful videos. Your videos are always clear and to the point! (and this one saved me some money)
Definitely want a review. I'd love to see a video going through each of the fender tube amps and looking at the main differences and pros/cons of each. It's so hard to work out.
A good & helpful video. Short, concise & to the point. Kudos.
super helpful tips! love the tapping on the input trick.
AMAZING!!! Diagnosed my problem right away. Thank you so much for this incredibly useful video!
That is an old trick I learned back in electronics class in school, 53 years ago. We also used an oscilloscope, something you probably have never seen, except in a museum or some old guys back room ,like me. That is a great amp . I have several Fender amps. Keep on picking Phillip, Sniper
Great, simple instructional video Phil - thank you very much
Philll!!! Love your chan brother . My knowledge has grown and have your channel to thank. Thanks bud .
ever since my dad brought his vibro champ out of storage ive been looking for a method to test the old tubes im definitely going to try this now
Love your videos Phil. Keep them coming. The video with TTK was a awesome idea and really interesting.
Thank you for the knowledge on this! This is amazing and helped me fixed my problem on my Marshall amp!
My HRD had turned thin sounding and developed a 60Hz hum. Chopsticked my tubes per this video and the two 12AT7s I had put in 3yrs ago to cut the volume were both dinging high-pitched. Put the 12AX7s back (from 1998) and it's back to loud but no more hum and thinness. Thanks for the tip! Saved me a trip to the local tech. I'll switch to JJ's when I need new tubes.
Yes Please. A review would be awesome. Looking for a new amp and was always intrigued by this one. Thanks
Have always wanted to add this amp to my wet/dry/wet rig! Yes please review!! Thank you!
Great video and excellent explanation of this issue and solution! Very helpful Phil!
Thanks so much Phillip! Now I could solve a problem I had with my amp which would make some loud bass tones at some frequencies / chords played.
This is why I am a Patron! Helping people fix their gear when they can ... and to know when they should not. Great job as usual!
Lol the three dislikes 1. The guy that sold the Amp 2.first guy to pass it up do to noise 3.went to buy it and it was sold 😔 TFS another great video!

Due to noise?
@gohjohan

Due to kicking themselves. I saw a Fender Blues Junior for sale on Reverb few days (or was it weeks?) ago. Listed for AUD416. Condition was declared as very poor due to some high pitch noise when turned on. Was sold the very next day when I checked......
Yes Please Phil, I would love a review of this amp.
Thanks Phil! Just subscribed to your channel and i learned something new right off the bat.
I've been using your vlogs for making repairs and adjustments on my guitars; great stuff! StewMac may want to thank you, too, since I've been ordering tools from them because of your recommendations; yeah, expensive but worth it. SM has unique parts, too, so I may be ordering from them, also. Anyway, thanks many times for your help.
My amp was making a crackling noise on my saldano slo 30. Tap like you said, already had 6l6 tubes. Tap the 6L6 yeah definitely not good. Let cool down replaced it turned on. Awesomeness!! Finally play not worry about the crackling! Might be small quick thing for you. But for us it really helps us out of big holes! Thank you!!
Everything from your channel has been helpful
I love the 68' Vibrolux! Greg Koch turned me onto them and I'm playing it for years now. One of the most underrated Fender amps!
Phil, wow. What a great piece of information! Thank you.
I suspect the same thing was the case with a deal that I got! I thought the tube was microphonic but it turned out it was being pressed sideways by the spring inside the cap. The small protrusion at the top of the tube had found its way through the side of the spring somehow. Works great now!
Awesome! 👩 very good information. You deff can hear when a tube is bad having that pinging sound, thank you.. 👩 I have 2 tube amps and one of them is losing power while I'm playing and I know it's one of the power tubes, but I don't know which one...
Thanks for that .. I have a old 8040 ValveState Marshall combo that sounds terrible when it gets hot after a while . I thought it was the preamp valve & that confirmed it . . .
Hey Phil I have a couple of tips that really make this amp shine even more. 1. Run a jumper from input 2 on the vintage channel into channel 2 of the custom channel. Plug your guitar into channel 1 of the vintage channel. Balance the 2 channels to taste. 2. Run a BBE sonic stomp in front. Try it out I promise you will be happy. I love these amps. In fact I love them so much that I originally bought the 68 custom deluxe and fell in love. So I also bought the vibrolux. I use my American strat deluxe with the deluxe and my American Tele deluxe with the vibrolux. I think that a review is an excellent idea.
Hi Phil, Great practical demonstration of diagnosing a microphone tube, yes, please review the amp. Am interested in how reliable and robust new gen Fender amps are.
OMG you are a life saver Phil! Thank you need to do this on my Uberschall Bogner amp. Cheaper than pay an expensive tech.
I just bought a valveking combo and have the same problem, thanks for the tip
I fixed a fender hot rod with this info. Thx. My endless pursuit of decent affordable guitars and amps has cost me more than it’s worth. I’ve lost so much money on deals and following advice that now I’m stuck either selling at a significant loss again or trying to get through the headache of making what I got work. The hot rod is not kind to humbuckers or to mistakes. The OD channel is just unusably bad. I felt like I arrived by getting a tube amp, lol. I think I’m going to start over with a PRS and a katana.
Very helpful and informative video! Thanks Phillip - you ROCK!!!
I learned 3 things. Thanks you so much for the video.
Great demo Phil! Thank you.
Definitely review that amp. I've been a high gain guy most my life but now in my older years i've been looking to find a great clean tone.
Have a Vibrolux I got used and well worn when I was 12 in 1972. Great amp, still has the original blue back Jensens.
yes phillip !! would be great if you do a review of the vibrolux !! by the way, great stuff you post as always . thank you for all this knowledge.
Thanks Phill, I don't own a tube amp but never hurts to learn something about them
Yes please Phill. we would like a review of this amp, Thank You, Cheers
Brilliant, Sir! Just subscribed This was GOLD
Great video, Phil! I'd like to see a review on the Vibrolux!
Thanks for this, found out I had bad power valves causing massive volume drops and a microphonic tube as well haha!
Crazy, what great information. Thanks for the video.
Brilliant informative amp Phill thanks.
All the info right there. No filler 👍
Hey Phil, Very cool video. I have a Fender Bassman 10 / 100wt from 1974. Now I know how to test for bad tubes.

Hey Phil. I really enjoy your content.
Totally do a review! I feel like lately the good old Vibrolux Amps have been out of the limelight, with so much going on with the guitar scene these days. Magical Amps
Yup, A review please! That thing is awesome, Great find bro, I guess it pays to KNOW YOUR GEAR! Lol... Thanks for the tip on checking out tubes 🎸🎼🎸🎼👍
Good instruction. Thank you.
Thank you for the great info Phil!
Great video, I learned a lot. I might have missed the cost of the new tube.
very helpful, thanks for doing this
Awesome man. I ran into this with an old Traynor ycs 50h. Maybe you could go a little in depth on biasing a tube amp sometime! Thanks, Phil!
This was really helpful, thanks!
Wow phil im really glad i found yer channel....thanks again
Wild. Great fix. Thanks for the tip!
Thanks for the informative video.
Thats superbly good tips.
Yes Phil please review the amp. Thanks.
Thank you for the video... I learned a lot...
My brand new Hot Rod Deluxe had a popping metronome from a bad tube 😂 I’m annoyed but happy I found the problem. Thanks my friend
Valuable tip for an easy DIY fix.
Yes. Would love a full review of the amp.
Always loved the vibros. Love the 2x10
Thank you soooo much for this video. My amp was pissing me off till I saw this. Tested and got the tinging sound.
Great tip Phil!
AWESOME...thanks for helping brother
This brings me back. My mum always used a wooden spoon ... she was an expert at tubes.
Thanks for this video. I plan on trying this method to diagnose the squeeling coming from my Meatsmoke's clan channel. Hopefully its just a single preamp tube
Excellent video, cheers
You have the best guitar channel on youtube. Amp review!!!
I’ve got this amp as my go to.. I can’t express in words how much I love this thing, It would be cool to hear your thoughts on it!
Got a Deal like this Amp was a Laney VC30 210 30W Class A all tube, looks like this was sitting on the store for a looong time got it for 450usd not sure if its damaged or something since at the moment i didnt knew anything about tube amps i watched many videos and this one will probably help me determine if its in good shape
Phil coming in with the wisdom!
Love to see a review thanks.
Thankyou, very helpful
Thanks man. Much appreciated
Thank you for a great video real helpful
Had the exact same issue with my Super Sonic 22 combo, and thankfully a replacement 12AX7 I had lying around in a bin did the trick. So I can verify this WORKS, people!!! :)
Happy to see no thumbs down! Keep these awesome videos coming!
Thanks for a great video.
I finally got the 🥎's to take the covers off and tap them with a piece of wood(I used a shim). To my ears the power tubes sounded fine. Two preamp tubes sounded like broken glass. Much cheaper fix. Now the only decision is what preamp tubes for my Dr Z-Lux. Thanks for the tip.
well done bud very helpfull top man,
Brilliant Phil.
I have a Fender Vibrolux that has been modified so the left channel acts as a preamp for the right channel. Sweetest sounding amp I've ever owned!
