Hello everyone.

This week I had a very profitable a100 second hand buy.
Among all the goodies were two A111 VCOs.

I have connected both and immediately found out they were both out of tune with each
other and with my a110s.

I also noticed on my oscilloscope that the sawtooth from these babies is a rising one
instead of a falling.. this is normal eh

But the most scary thing is that one of the a111s has a clear defect.
If I turn the Pulse Width knob above the 5 position it starts to influence the pitch and the
amplitude of the sine, saw and triangle waveforms!!

I have been trying to tune the oscillators but I first would like to know the whole story
before I continue...

Thanks,

Ernst
