Hit a new curve with this unit. What can anyone tell me about copper oxide rectifiers? There is one of these in the VOM section. I'm presuming to rectify AC voltage before the meter. It has a variable resistor inside labeled 233 ohms. Would this be for calibration purposes? How do I test this unit? If bad, can diodes be used to rebuild it? The whole assembly is built into a standard 4 pin tube base. Any info is appreciated. Unfortunately, the paperwork I got only cover usage instructions and a schematic. No information on how to calibrate it. Take care, Gary
