Voltage Processor - CVP - Build

Though not the sexiest module in your modular rack, the voltage processor is very useful and in fact essential to get the most out of your system.

I've got a quite a few in the Buchla format.
These are great pages concerning the Buchla CVPs

Today I'm building a Euro CVP From Manhattan Analog
The build notes are here


Pretty easy build. the components are marked on the PCB.
The trimpot is 20k

The two ICs are basic Op-amps ... a TL074 & 072


There are two 50k and a 1M pots , The 50k are Linear.
I've seen builds of this with the 1M being either audio or linear (P3/Glide is the 1M.)
I'm building this with 1M linear.
I'll build another one with a audio pot and see how it behaves.





The anode of the LED goes into the square hole.

 to be continued......

    Thank you for sharing it, essentially the Intel Core i3-10100F Processor is a 14nm processor from Intel's Comet Lake-S family of desktop processors. The Intel Core i3 processor is an excellent starting point for a quick and responsive PC.
