Honestly, bit of a pain in the ass to build with a very compressed board layout. Most of the drilling was just done by eyeballing everything and I think I got PRETTY close.
Using a pair of EAA91 with starved heaters as the clipping diodes, with a switch to disconnect one side of the clippers - gives you a shifting DC point with attack, which kind of emulates what tubes do.
Sounds pretty good. Still having issues getting the gain control to sweep properly (original called for a linear pot with a shaping resistor which had 90% of the gain in 10% of the rotation, straight log was about the same but adding a more extreme shaping resistor seemed to have gotten it sorted out).
An interesting way to use tubes at least!
