[2858] Q&D Comp 1

Date: August 20th, 2023 | Comments : [2] | Categories: DIY.

The prototype of the Q&D 1 compressor. The schematic is still on my web site somewhere. It used the SSM2165 vca chip which is unobtanium these days.

I have a tube of about 50 of the SSM chips that I plan on selling with a pcb at some point. The proto pcb for it has even been made and is in my shop. I just need to get around to tweaking the values since the design is not the same as the basic Q&D 1.

A few questions:
1) Any progress on the “tweaking the values” front? :^)
2) Are the SSM chips of the 2165 or the 2166 variety?
3) Is the new PCB a revised Q&D 1 or closer to the Q&D 2?

Very interested in where your compressor work is headed.

Thanks for all the great content on your site. Much appreciated.
