3046

[Ken MacBeth]

Paul, I've been building Prodigy oscillators for some
time now. They are a great building block for more
sophisticated designs, and extremely close to the
minimoog mk2 oscillators. The nice bit is that you
don't need to go hunting around for TC resistors to
keep them stable. Problem is though, any time I use
the 1A regulators, the transistor oven blows. Someone
once suggested to me that while 3046 is cold, it will
drag to much current from the 1A regulator and then
blow. The bit that blows by the way is only the
heating element. The rest works fine. Are you familiar
with this circuit? I think it's at Anders Spontons'
site. i've actually been looking at designing an LM723
based PSU for future projects, as I only have a few of
the now obsolete LM79M12's left.
