What is the Optimal Internal Temperature for Germanium Fuzz Face???

[Chris Brown]

Just out of curiosity... I'm sure someone has an idea about this...

        What is the optimal temperature for the inside of a Fuzz Face's enclosure to keep germanium transistors at a stable gain??

I've experienced the overheat thing a few times... outdoor in Texas summer or inside on a hot stage, sometimes by the 3rd set the FF loses it's warm goodness... other times (relative humidity?) it functions as expected.

Any thoughts?

I would assume the optimal internal temp for a fuzz face would be whatever temperature the transistors were in when they were biased in the circuit. That is if someone was there tuning the transistors to the circuit and not just tossing them in with the usual 33k/100k/470/8.2k setup. I guess someone could purposely build one in a high temp environment in preparation for a situation like that but its really just easier to throw an external bias know or build a more temperature stable silicon hybrid fuzz face.
