How to replace 1/4" input jacks on Vintage Fender tube guitar amps easy fool proof repair method 

Some of the best tips are so simple and elegant. Why didn’t I think of that? That input jack tip is great, thanks!

44 years to the day and the California VibraChamp gets a NEW LIFE from DLab !!! Great Stuff Terry as usual !!

Hello Terry!! That tip about wiring the jacks that way first before permanent install is a great idea!!! that method could also be used to wire potentiometers or selector switches should that need present itself in future projects that have tight internal spaces like these amps do have!!!! Great idea !!!

Terry, Bless you for sharing your wisdom with us:) God Bless and Protect you and your Family!!!

Thanks for the "Input-jack" tips and the resistor up--grades. Your channel is beating ""Kojack" on my top 10!

Awesome tech tip!!!!! Thanks Terry!

FWIW .. I like to use RG-174 coax for the shielded cable to the input jacks. It has a small diameter and is easy to dress 😁

+1000 on the jacks. Thanks for that bit of wisdom

Pro tech tips are always handy thanks!

As a guitarist of 60 years, I was playing back in the days when not every player had an amp. I am convinced that Leo understood this, and that often, two guitars played through the same amp. Since chords are louder than single note lead lines, it was necessary to reduce the volume level of the rhythm guitar, hence the resistors on the second input of each Fender amp channel. Just my opinion, of course; but since I am a "know it all," you can bet I'm completely wrong!

Absolutely love your videos , been watching them all week 😌 would love to see your take on a tone king Imperial

Thanks for the great tip on wiring the input jacks! Excellent!

About 10 years ago, a friend asked me if I could replace the input jacks on his Fender. (as I recall, it was a late90s or early 2000s Concert model). My friend is a very well known guitarist in this area, and knows most amp techs personally. He told me that he took the amp to a few different techs, and none of them would even take the job, so he asked me. I accepted the job, and then found out why no one wanted the job. To access the jacks, the entire circuit board had to come out, which included removing the tube sockets from the chassis. The tube sockets were not soldered directly to the board, but, instead, had short wires between the socket and the board, complicating the process. The labor charge (at that time) would have been around $150.00; to replace two $5.00 parts.

Good to hear you use a guitar to test with. You don't need to know how to play and it's a much better sound source than a signal generator. Nicely done. 🙂

Great job Terry..Fab oldie, well tips..Ed..UK.😁

Excellent tips for coaxing some more gain. And, yes - thank You for the tip on the jacks. That's gonna be so much easier!

Love the channel. I have sort of a silly question. I've got a ten year old home theater in a box and one of the channels will spontaneously crackle like crazy. Turn it off and on again and the crackle stops... for a time. While I'd love to have the excuse to upgrade, I think that the issue is likely just some dirty or corroded connections. (It sounds like the sound that you'd hear when your guitar pots are dirty and you turn the knobs - but there aren't any knobs - just spontaneous crackle.) What's the proper way to clean connections. The only troubleshooting that I did was to plug a different speaker into the channel with the crackle, and it's the channel, not the speaker. We're not talking lovely vintage gear - just dirty old gear.

I've been using that method for years! (Actually, no I haven't. And I feel like a dope for not having thought if it myself.)

Nice guitar playing. 👧

Great idea always curious about speaker jack wiring also this will work the same way for those if you ever get round to it perhaps show how the speaker jacks are correctly wired also. Terry I am trying to reach you via email had a question about voltage at bias board and some other questions. ive followed your other videos about bassman and purchased the same meter to be able to make correct selections in testing voltage and - bias at board and pin 5.. The videos are very helpful.

very good job! congratulations!

Hello. Ever since Whites metal detectors have gone out of business, it's difficult finding parts. Is there a part number for the TDI Pro on/off Gain Switch or a generic switch I can use? What is the part called a rotary switch 12 volt with on/off? Can a non tech person do the repair for a switch like that or should I send tbhe whole unit for repair? It doesnt look to hard to do but I havent opened the detector. Thank you so much for any help.

I see your reverb account is devoid of any amp offerings as well as your website. Any news of upcoming amps for sale?

Terry how did you wire the 1 meg ohm resistor from the ground to shield then to the tip?

Great advice!

Why would changing preamp plate resistors from 100k to 220k up the gain? Wouldn't a 100k allow more voltage to the plate from the power supply node and 220k limit voltage?

At what temperature do you keep your soldering iron to ensure you dont burn components?

Nice!

You mentioned that the Cali amp had the incorrect type of input jack. What did you mean by that, and what is the correct jack type?

im here so early that thumbnail isnt even loaded

Ah ha, I used a cardboard jig for those.

That poor board.
