I picked up a well loved Ampeg Super Twin Echo 2 that had spent some time sitting in recent years. It sounds amazing but it needs some TLC to be fully operational; the issues it has are:
-loud hum when the channels aren't bridged or when an instrument isn't plugged in
+filter cap cans have been replaced and this did not solve this issue
-reverb bleeds even when switch is off
+haven't been able to track this issue down as all components in reverb circuit are within spec
-absolutely can NOT get the tremolo to work
+after replacing all caps in the tremolo circuit that had drifted, still no luck. Went back and replaced all components in the tremolo circuit - still no luck. Swapped all factory Ampeg tubes out for new ones {even though they tested strong} - no luck.
When the tremolo is engaged I do get the momentary dip in volume but nothing else.
I've successfully repaired Ampeg tremolo before on two other Rockets I own and the circuit is nearly identical. What else can I check?
Thanks in advance.
