[QUOTE="Telmar, post: 162566, member: 4611"] Here is the solution ! The "Herbert" uses an OpAmp, probably for some active filtering, that needs a bipolar voltage, usually +/- 15 Volts to work. Here is the way the current flows: 1.) Voltage input at pins "J" (positive) and "H" (negative) 2.) 22 Ohm resistors R30 (positive) and R32 (negative) 3.) regulators "IC1" (78L12 / positive)and "IC2" (79L12 / negative) 4.) OpAmp pin "8" (positive) and pin "4" (negative) So all you need is to built a tiny +/- 15 Volt (+/- 13,7 Volt in theory) power supply and connect it to pin "J" (positive) and pin "H" negative BUT PLEASE CHECK MY DRAWING ! ! ! I AM NOT RESPONSIBLE FOR DAMAGED OR BURNER EQUIPMENT ! ! ! [/QUOTE]
