Harris RF-550 Parts

[W5CQ]

Does anyone know a source for Harris RF-550 receiver parts?

I've had a failure of the VFO/BFO/Translator module (Harris part nr. A2A15, which consistes of two boards, A2A15A1 and A2A15A2).
I could use any or all of those parts or the Harris part nr. MRK-1001-0189 extender cable which would allow me to trouble shoot the failed module

Or a source for the Wnichester Electronics plug and socket part nrs. MRAC20PN7 and MCAC20SN7, which would allow me to make-up my own extender cable..

The Wincheater Elect. site no longer lists those part nrs. nor does Allied, Digikey or Mouser
.
Good dxing, fellows -

Thanks, Martin - you know your parts stuff!

I should have lncluded Tornto Parts as one of those venders I've checked. They actually have one RF-550 part - the power cord, which has a unique screw-on connector!

Since my original posting, I've discoverd that the Audio Output Board, part nr. A2A6A2, has numerous failed componets. This board takes the BFO signal and mixes it with the detected audio to produce CW/SSB output, so it may be the real culpprit. Did I mention that the receiver works fine in AM, but has no detected audioi in the CW/SSB modes?

Trouble-shooting this puppy is complicated by the tight, closed constuction (read, "Tank-like") Harris employs to make the RF-550 so free of image and other spurious emissions. That construction is an operational blessing and a trouble-shooting nightmare! I really need the extender cable!
