HEATHKIT HW-100 SSB RESTORATION
Today I prepped the HP-23 power supply for the update kit that is coming. All the capacitors, resistors and diodes inside are removed, as are the tie strips. A single PCB has the replacement parts installed and it will sit inside the power supply enclosure.
HEATHKIT V7 VTVM RESTORATION
I took the VTVM apart, checked the circuit board and it seemed fine. I powered up with the parts loose and it worked perfectly. Put it all back together, and the bad behavior is back! I did this a few times and can't figure out what intermittent problem is causing this. Frustrating. I will have to start tracing circuits and monitoring voltages until I can narrow in on a suspect area.
