Had me a few "wtf" before I realized only intersecting lines with dots actually connected. Other than that I lack opinions or input for that matter. Hopefully someone with access to a breadboard can help you out.

I'll give it a shot. I tried to breadboard a condor=fail, so I have a breadboard free and would like to have a cabinet sim . Right after I cook up a Dr. Quack PCB

Sorry, cooking circuit boards turned into drinking whiskey and aromatherapy, plus waiting for a while since I'm using Persulfate which apparently loses it's juice. I tried heating it back up and it wasn't very effective, ended up whipping up a fresh batch and blowing the rest of the night getting hammered. I try it later today.

Rob,

Maybe a trimmer pots in place of the 12K to Q2 drain could help bias it, or maybe the 12K at Q1 emitter? Could be a biasing issue since the original uses the 2SK208 ???
