Awesome! That was you? I think I remember that Frank Zappa used these during the Ship Arriving Too Late to Save a Drowning Witch era. I've looked for one used for a long time, and have never seen one.
A better one is one I learned from Colin Sanders of SSL. Put a fixed ref current into a THAT2180's audio input. Use Ec (or Ec-) as your control input. Do an I-V on the output as usual. The output will be exponentially related to Ec. Add tempco at the Ec input buffer.
Colin used it in the Plasma meter ramp generator. That's why a gold can VCA sits in the meter bridge. I think he personally gets credit for that one.
I love the sound of that Cure Album.
I read that most of the kit was micked with cducer mics
to get rid of all ambience sound!!
Let me see if I have a blue-line on that one. Bill H. did the Timewarp and it was under way and going into production right as I came on board.
Those trimpots IIRC set the bias and clock null of each MN3XXX. Don't remember the part number. Was it a 3001?
Recapping should've taken care of the hum. Don't know why it would be delay time dependent. There are probably some smaller electrolytic Cs on the outputs of the 78/79LX regulators. You might want to change those too.
What line voltage are you running on? I'm wondering if the regs are going into dropout as it pulls more current at higher clock rates.
Will look for the schemo.
