Tube Synth

[tomg]

You have a point here Harry. You could set it inside a thermal
cooler then ice the outside of the cooler and achive the same effect.
Someone said Berry suggested glueing a styrophome  peanut
over expo-converters. When I first heard this I thought it was funny.
I have changed my mind. My apoligies to Berry for the expo-happy
meal comment..I though it was funny...anyway  I think a squirt of insolating
foam on a  diff-pair with a tempco glued to it is a real solution to temp
drift.
A vacuum tube would work too I guess....;-)
