I’ve built the twin peaks tremolo (TPT) before using David’s o band it worked fine but I’m having a heck of a time getting the vero version working.
The taplfo seems to be working. The tap led seems to flash and change when I adjust the depth, rate, symmetry and multiplier controls.
My problem is I can’t seem to bias the lfo properly. If I do an audio probe I get signal on the ldrs but no matter what position I set the rotary switch to I can’t seem to get a signal at the output.
My led (d1) is light and I measure 1.8v across it so T1 should be outputting the proper voltage.
The only mod ive done is use a 50k trimmer instead of the 25k trimmernfor the offset.
Any suggestions for what to look at? Could the lfo chip be dead?
