This is my third PPCB compressor build, after a Boneyard Delegate and Thumbsucker. They’re all great, but I find this one particularly easy to dial in. I plan to use it on my bass board.
I can’t recall if it had already been mentioned here, but it is a little tough to see the orientation of the transistors on the silk screen. I did originally install two of them backwards, but was saved a trip to the troubleshooting forum by… wait for it… visual inspection! Thanks for all the old hats who continually harp on that.
I did make the following substitutions:
- MPS4124 -> 2N42124 (from Small Bear)
- THAT2519 -> Cool Audio V2519
- KA4558 -> JRC4558D (and one RC4558P)
Ignore the lifted resistor…..
