[sdiy] Moog 921A/B output levels

[Michael Zacherl]

Hi Dave, thanks for the reminder!
Looks like, on the 921B sine wave amplitude is as twice as much and pulse wave wouldn’t be really  available without the 921A controller.
The only old Moog Modular I had at hands was very atypical, had only two 901B VCOs without 921A modules but 2x 5 custom Sawtooth oscillators. 
And all signals appeared to be very hot, but I didn’t measure them back then.
