Scratch that! Solved. I'd bollocksed up the depth pot wiring.
Hey all. Latest trivibe is passing dry signal but doing bugger all else. No modulation at all, switch and pots do nothing. I have one working trivibe already, using the John Lyons layout from the ROG website. This one thats not working was built using this (supposedly verified) layout: (built on a whim, the working one is in a 1590BB, I really like the effect but would like it more and be able to get more use out of it if i could squeeze it down to a smaller enclosure)

Here's shots of my board, and voltages below.

My untrained eye doesnt see anything obviously wrong with these voltage. Can anyone assist? I've even taken the voltages from the working one to compare, Here's what I got from the OTA from the working (John Lyons) layout for reference: (much the same, pins 5+7 are about half a volt lower, 10+12 are about half a volt higher. the rest look on the money)

Any help or insight would be appreciated, Cheers!
