Hi, everyone. I have a simple, but thus far very frustrating problem with a signal control circuit I've designed.
The circuit sims fine in Multisim and works fine in one direction on the breadboard, but when I flip the switch, it stops working like I flipped the off switch. The signal needs to be ±10VDC and the amperage is negligible. I don't understand what's causing it. It works fine when I hook it up directly to a variable power supply, but when run through the regulator and pot it doesn't work right. Please help.
