Re: Precision heater chips (fixing temperature instability)?

Hi all,

I was asked by a musician if I could do something about the temperature
instability of his old Moog 342 synth. At the core of its oscillators is
the CA3046 transistor array: http://www.linetec.nl/electronics/moogosc.jpg

This design turns out to be quite sensitive to temperature changes ...

I forgot to mention that earlier on, I alrady tried adjusting the internal
temperature stabilization, but that doesn't appear to work properly.
