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 73 Randy |

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. http://www.qsl.net/kk4kf/hw9-mods.html -- Martin E. Meserve |

Some info on the PSA-9 at URL:
