I pulled my front panel today. I don't see D49. Looks like I'd have to add it. I don't know how old this radio is. I bought it on eBay. Several spots are open below D49's location, as well. No mods from previous owner. No 11 meters at all.

worked on mine a few years ago, pretty sure only one I had to remove, didn't have to add anything:

I guess make sure that D-48,49,51 Are removed and that D-50,63 are in place

  • @ ButtFuzz:
    on the connector with the green wire, if you short that to a nearby black wire, the power supply will turn on. (for use as a bench supply or whatever)
  • @ ButtFuzz:
    And IIRC, the purple wire is -12VDC, but that is from memory and it does not serve.
  • @ ButtFuzz:
    So if you need, say, 7v, connect + to the Yellow wire and - to the Red wire.
  • @ ButtFuzz:
    or or you need 9v connect + to the yellow wire and - to the orange wire. note: not all PSU's have the orange wire nowadays, as many manufactures had the voltage regulation on the motherboard, and all the power supply gives is 12 vdc
  • @ BJ radionut:
    Thanks ROB will check it out!~!! got to clean the work bench a little make room for that big case :)
