what might stop working...

[andydeedpoll]

in a Fender Princeton chorus (one of the old ones.)?

my amp stopped working after about 15 minutes of playing in band practise last night. i use a fairly large pedal board, and then a TC Electronics reverb unit in the effects send - this has a level meter, and i could see that the signal was getting To that unit, but not back again. i changed all my leads, tried it straight from guitar -> amp, (checked my guitar into the PA, just to make sure it was nothing there) and tried some one elses guitar into the amp - nothing. i also tried guitar -> TC Electronics reverb -> effects return, again with nothing.

any thoughts on what this could be? i know Very little about amps, but my gut reaction is that this is something to do with the power section or the speakers, because it appears that the signal is getting to the effects send fine, at least.

any thoughts?

I had one of the red-knob Princeton Chorus amps for about 10 years or so. It quit working one day out of the blue, with no warning nor due to any abuse. It just died.

Then one day about a year later, out of desperation, I plugged it in and voila! It worked! And it worked every day from then until I got rid of it.

Maybe yours just needs a vacation too

It's called percussive maintenance. Sometimes it makes things work, sometimes it makes things worse.

a fuse? maybe loose?

It sounds like some electrons must have got a bump on their heads and got amnesia-they had no idea where to go so they were lost...
When they got the next bump they snapped out of it and journeyed on to the speaker-and viola~sound was heard again

I think I read that explanation in an electronics textbook. No wonder I've never been any good at understanding that stuff: its magic!

Isn't it funny how giving a piece of complex electronics the simplest possible adjustment and it mysteriously works? Its like Fonzie with the jukebox. Did you go "heeyyyyy" afterwards to make sure that it continues to work? That's a very important step.

Now if I could only get that to work with computer programs, I'd be set for the rest of my career.

i love how one person replies for the genuine question, and lots of people reply once it's been solved

you did all make me giggle a fair bit though, so that's alright
