Heladito problems

[The Iron Chef]

Hi all.
  I've etched and populated a board based on the tonepad clone of the Small Clone, (Heladito). I  think that my build just doesnt sound like it is supposed too.  No "lushness" or any of the other attributes described in the tonepad build reports.  My build just sounds like a plain vanilla tremolo.  It can change speed and depth. I added the depth pot mod and the 2 speed range cap switch, 2.2/1.uf caps.   hmmm.  I guess that I'm missing something that someone else here can find what I cannot. I am including voltages and images.

Heladito semiconductor voltages.  both pots at minimum.

Hi!

If you get tremolo and no chorusing you are only hearing the delayed signal. The chorusing happens when the delayed signal is mixed with the original.check the 22k resistor between IC1a and IC1b.

Hej Oskar,

     Thanks for the suggestion.  the 22k resistor checked out OK.  Now I seem to have broken something as I'm not passing any signal now.  Time to audio probe!
