How to fix 1964 Fender Princeton Low gain weak tube guitar amp Step by step

Another great repair. From low gain to monster sound. I approached this repair systematically, hopefully to catch the flaw along the way. Turns out that the issue was due to past maintenance. Either way, when working on these old amps, always install fresh capacitors. These have been in service almost 60 years. Failure is right around the corner. These old amplifiers have beat the odds. Still operating and will continue as long as they get periodic check ups. This Princeton is not original, however still sounds great!

Amp sounds fabulastic. Love it when an amp tech looks around and finds stuff and makes it like new, when it ain't!

[@tommyhjelmgren2108]

Your guitar amplifier repairs are my absolute favorite! Great info!

AHHHH! Seeing the Snozzeramus Ungar is like seeing an old friend. You Know that when it shows up, there's going to be some serious $#!% going down! Please keep up the excellent work, Terry!

Nice video, very informative, but painful at the same time, seeing all those original parts being replaced only to find out they were perfectly fine and the problem was elsewhere (volume pot and input jack)!

Great video as usual.

I liked both tube choices. The bite of the original would suit live and the mellowness of the replacement practice. Both tubes, but switchable and twice as much output power... Guitar players are never satisfied... As it happens the channel switching on my Super 60 already does exactly that. And LOUD! Nice little amp. Thanks.

Snozzeramus is looking a little raggedy! Many, many repairs using that beauty. Great troubleshooting as usual!

wow, that beast of a soldering gun ..

[@pneumatic00]

Incidentally, if you lack a suitable Snozzeramus you can solder to a steel chassis very well by clamping the threaded end of a 4-5" 1/4-20 or 5/16 bolt in a pair of vice grips and heating up the head in a propane torch. File the head semi-clean if it's a rusty dog. Stop heating before red heat. Use it just like you would a big fat soldering iron. You don't really have to tin the bolt-head. Works perfect.
