New to the forum. I've joined in the hope that someone can help me figure out how to troubleshoot/repair the spring reverb on my HH Musician. The amp is in generally good condition. I've cleaned the pots, replaced the rotary switches, swapped the old 741 op-amps for NE5534 and replaced the PS capacitors for fresh ones. The 'Tone Correction' module still works fine and hasn't died on me yet.
However... I can't seem to figure out what is up with my spring reverb. The reverb still works but only if i pick very gently, if I strum a chord then I get this horrible blatty gated noise. There seems to be a problem with headroom in the signal.
Here are links to the schematics for the amp. there is not much to the reverb circuit assembly, I have replaced the opamps and can't see any loose connections or cold solder joints. The reverb tank itself looks to be fine, again no loose wires or connections.

Anyone have any ideas or come across a similar problem?
