I am finishing mine, finally. I found an error in the clock coupling
circuit etch. The diode that is supposed to clamp the voltage on the
transistor base is not connected to the base of the transistor, but
rather to the opposite end of the 100K series input resistor. I fixed
this (cut the connection to the non-grounded end of the diode and put a
jumper to the correct spot). I also DC-coupled (omitted the 100nf cap)
that delivers the ramp out of the VCO. This is the last module in my
queue for a while. Once my MOTM-650 arrives, the four cabinets will be
full up. I will update my website when this is all finished.
