Summary of Contents for System X S/H Noise

Page 1: ...the half circles f This signifies FET 2N5485 transistors Note the correct pinout as shown by the half circles Noise above FC logo This is the transistor used to generate the white pink noise Just a stock BC547 is fine for this But if you really wanna use that vintage mushroom cap BC178 that you pulled from a 1970 s Farfisa organ you go girl The PCB shows the correct orientation for BC547 BC557 2N5...
