[sdiy] HP 202C Low Frequency Oscillator

[elmacaco]

Yup, I found the BAMA, lovely place!  No 202C manuals though.

I love it, they call it a low frequency oscillator because it only goes up
to 100k Hz!!!

I meant in the picture, not in the counter!!

I don't think I will use this for it's intended purpose, not sure what I'd
measure with it, I'm going to play that big knob like a theremin!!  Delia
style!!

It's already getting somewhere, even though the knob is clockwise for lower
pitch, and CCW for higher pitch, it is very easy to get used to.

It sounds so damn good I don't even care that it only has one waveform!!

I did run it through my EFM waveshaper and had a bit of fun, but the pure
sine just rocks hard.

It will be a kick drum helper as well!!

Thanks to everybody for your help.
