Hmmm. Would you think the germanium transistor for the new Benson pedal is warmed to the desired operating range when it is powered? Seems like the LED also changes color as it gets hotter. I have wondered whether it might be simpler to put a small peltier close enough to keep the transistor cooler since that is closer to the way that the circuits are originally running.
