I have a new to me Heath QRP combo. The PSA-9 power supply has one resistor in
it and it is fried. I would appreciate it if someone with a manual could look
up the resistance/wattage of the resistor in the power supply

I thought that there was 2 resistors in the PSA-9. There should be a 1
ohm 2w resistor, and the 1500 ohm 1/4 resistor.

You may also want to check out the following web page. There are some
suggestions on power supply modifications.

Also check BAMA (BoatAnchor Manual Archive) -- may be a schematic there
