What is the Ge temp stabilizer diode mod?

thanks that cleared it up!  My mistake was not knowing that the base and ground were the same thing in this

You mean emmiter and ground right?

I'm just working with some leaky AC128s and I have to adjust the bias pot every 10 minutes! I suppose some transistors are worse than others for this.

I mean, in that circuit, ground and emmiter is the same point.

Yup, that's my Jimi tribute Strat that I put together.

Nice!
