[TenTec] Orion 565 service manual?

[Michael Tortorella]

Is there an Orion I service manual anywhere out there?  I have just changed
the power connector to a 2-pin mil-spec circular connector and in the
process mixed up a few of the internal coax connector plug/jack combinations
(rushing, I know, my bad).  Also, there is what looks like a high-current
diode right at the power input. I had to unsolder it to get at the power
connections, and I forgot which way it's wired in - with the cathode stripe
facing the closest side of the chassis or facing the heat sink end of the
chassis?  Dunce hat about size 7-1/2 I think :-(

Also, can anyone verify that the resistance from the + terminal to the -
terminal is about 36 ohms (with the PS disconnected).

Thanks in advance for any help.
