Vintage Problems

[Hobbit11235]

A guy that I know has a Fender Reverb/Echo 3 head, and it doesnt work.  I would like to know what the main problems were with these frigin things.  Okay, so it goes a little like this.  If you pulg it in and get the tubes warmed, it feels like its gunna do somthing.  The pot for the reverb dosent do anything and no sound comes out when everything is pluged in...the right way.  I have an odd feeling somthing has come loose in the circut and I would like to know if any body has a clue, or schematic :lol: , for me to work with.

no specific experience with that unit, but here's my ideas;

broken pots? That could stop the signal cold, and often they bear the brunt of any mechanical forces as they are part of the PCB mounting system.

Otherwise, faulty transformer maybe, or dud tubes...
