Coda Well-known member Sep 16, 2022 #5 Good luck. I’ve had a MK I TB built for well over a year now…every few months I get some new GE to test out…and the search continues…plenty of Peppermint, though…

How it turn out? Was your TB MK1 smooth sounding or did it have the Velcro thing going on? I was wondering if the transistors will a gain if a 100+ were too small. In that there was too much gain and compression. Thanks for your help. Regards Mark
