Hey!
The spring reverb on my Fender Blues Junior III does not work no more. Any tip on how to repair, is it most often the Accutronic itself or some malfunction on the printcard?

Likely the tank has failed. This can be easily confirmed with a meter.

You may have a bad connection somewhere, that would be the trickier one to fix.
But a good tech should be able to trace it no problem.

The easier thing is the tube driving the reverb.
It could simply be a bad tube.
If you have a spare 12at7 or 12ax7 swap it in the correct V position and try it.
If you don't have a spare you can try swapping the pre tubes and note any changes.
It's also possible that the tube driving the reverb is not seat properly.
Simply remove that tube and re-seat it and see it fixes the issue.
