Since this is a complex build including an LFO I would like to mention that this is an excellent opportunity to use an Audio Probe to quickly check the signal path not only confirming audibly the LFO but seriously narrowing down the area of the board to focus on where the Audio Path check would reveal a fault. Voltages will reveal that the LFO is working and much more but an Audio Probe is also an invaluable tool for listening for where the fault lies and helps beginners solve issues.

Be sure to always make sure the Pot is full Clockwise when testing for phasing as a SLOW phase might be inaudible.

Still provide test results please for Wilkie.
