Blues Jr. Broken Reverb help

Postby surlybastard » 30 Dec 2013, 19:44

So I picked up a Blues Jr. used, only thing wrong with it is the Reverb does not work at all. I changed all the Preamp tubes (is the reverb even tube driven?) and that didn't do anything. The reverb is dead silent no matter where you set the knob, I tried hitting the tank to see if I could get it to make any sound at all and there's nothing. My next move was to take the tank out and here's what I found:

One of the small springs that holds the pan (is that what it's called? I don't know anything about this stuff to be honest) is broken. My question for those who know: Is this the cause of the reverb being silent? When I saw it my first reaction was "Oh there's the problem" but the more I thought about it the more I was concerned I couldn't get any sound out of the reverb at all, which leads me to believe the problem might be somewhere else.

If fixing this small spring will fix the reverb, is it worth trying to find that spring or should I just replace the whole tank?

Thanks!

Try fixing the spring and see what happens. It looks like the tank is touching the jack at the disconnected end and this could kill the signal. Replaceing would be costly.

Thanks for the help everybody, what I ended up doing was cutting the cables to the reverb assembly and soldering them (I figured I couldn't break it any worse than it already was) but that didn't work. I eventually figured out the output jack was the problem but still couldn't figure out how to get it to work so I just gave up and ordered a new tank. At least I tried though!
