Hi Ken and all
I have had something fail on a working CGS48 VCO on my BOG panel build.
It was working just fine ; when powered up the other day the output sounded no signal at all for about 12 seconds and then nothing but very high pitched output.
Way above the range that it's supposed to be putting out.
The Freq pot changes this pitch.
All inputs like 1V/Oct , FM etc seem ok.
I have swapped all the IC's with the VCO next to it except the LM394 (as it has a Tempco over it). No difference.
