[sdiy] Moogey jitter

Ahh, I see. Now everything is clear.

Well, it would be interesting to hear how the sum of the two VCOs
(clean and 2033) sounds, compared to two clean VCOs. (Both
cases with a slow beating, like 0.5Hz, and then the jitter on top of
this.)

I think I had the whole heater oscillating in the 100kHz or 1MHz range
before I decoupled it. I never went so far to notice a slight oscillation
around
100Hz at all. (Which isn't to say they weren't there - just to say the idea
never occured to me to look for something like this, back then.)
