Way to go Paul !!!
Larry (drooling and waiting for VCOs). Got so desparate I bought a Hammond
Tonewheel organ today. Talk about tracking. <grin> I only did it because
of that "power" thing. It's the only "oscillator" (using that term
loosely) that we (power company) have control over the stability and
tuning. HAHA. BTW, if anybody thinks that 60Hz (USA) is a static,
constant thing, e-mail me privately.
