Just finished up this Mk II Tone Bender basted on the PUTB board. Other than messing with transistors and a little trouble shooting with help from Barry, I didn’t mess with this one. Transistors are a Russian with an hFE of 70 and a pair of 2N527s with hFE of 86 and 115. Tried out a couple of official Tone Bender sets but couldn’t get them to bias well and their tall skinny cases were going to be hard to get into the 1590B. The mixed bag “set” works just fine with lots of fat, fluffy, screaming fuzz.

And the guts:
