Just bought a new A-188-2. The Delay time does not go low enough to produce any clock 
noise at all, as it does with my A-188 2048. I'm wondering if this is due to one of the blue 
screwdriver trim pots on the back of the module but don't understand the way they are 
labelled or which one you would adjust. Do the A-188-2 modules ship with a certain 
setting that can be adjusted? Currently, only chorus sounds (an amazing range of divese 
chorus sounds) come from all outputs regardless of the delay knob position, no clock 
noise, no sound deconstruction, seems contrary to the manual. Thanks for any quick 
words.

Sounds like a faulty high-speed vco. I suppose that the heated transistor
array, that is used in the exponential converter of the HSVCO (CA3096), is
defective and should be replaced. Please contact the dealer where you
purchased the module. If you are able to replace the CA3096 yourself (there
is a socket for this circuit, no soldering required) they could send you one
for free - provided that the have the spare part in stock.
