That is a rare beauty ! My workbench used to contain several pieces like this. I got my start in electronics testing power supplies for RCA.

That is a great unit Ken, I love it. Eico, Heathkit, Knight etc, produced great test gear back in the day, and they continue to work today. The chassis looks pristine on your unit and a good job on finely calibrating it too. That is a class unit for sure

Ken, nice video. I also have a 1030. The only recommendation is to replace ALL the capacitors. The tester you were using does not show you if the capacitor is leaking. With such high voltage, you can reform some capacitors, but with piece of test equipment will work better if the capacitors are replaced. Also the Bleeder resistors across the 2 caps in series should be check to maintain a good balance across the 2 capacitors. In my unit once I set the unit to Zero Volts, and then set the unit to 400 volts, their is no interaction between the 2 calibrations. You were going back and forth, I suspect leaking capacitors, but that is assuming all the tubes are OK.. This will result in a piece of equipment that will give you many years of service, with no worries about failures. Also the new capacitors will preserve your tubes and they will also be happy... I replaced all the caps in mine, 2 bleeder resistors and a few other resistors that were out of tolerance when it arrived a few years ago. Robert San Diego

Far better design than either Heathkit models IP-17 or IP-32. You have full wave rectification over a voltage doubler. Should get a higher amperage output. 400 VDC at 150 mA' s for B+ and -150 VDC at 2mA's bias. Three filament voltages are offered but be careful with any power supply like this unit which can kill you if you are not careful using it with any probes incorrectly. Great and useful piece of test equipment you got there Ken.
