On my latest builds I used an LED on the cathode and it helped give it a much deeper trem. On the beating side of things, lead dress is still important. In one of these amps if the B side of the reverb recovery was too close to the wires / terminals of the trem circuit it I could hear a faint beating/ticking.
Thank you! You have so many threads/posts, can you link me to the final schematic?
