[Milsurplus] USA RU receiver connector wanted

[Robert Downs]

I'll point out that not all RU's use the same connector for that location.  The Liaison sets (like the final models RU-18 and 19) use the 10-pin 133.  The Command sets like the RU-16 and 17 use the 11-pin 233.  Parts of the dynamotor, junction box, connector and receiver wiring is also different between the two groups.

Ben, I seem to recall the connector number is 233, but I don't want to look for my RUGF manual now. Can you verify that is the connector?
I should have plenty of these. 
For the chassis plug, "maybe". I don't think I kept any RU junkers. Next week, I can go look thru my stuff for both. 

BTW, since the RU is so broad tuning, I am wondering how it worked out for the long range CW liaison role. People find it unusable now on HF.
The only thing I can think is that in CW mode, it somehow acts as a direct-conversion receiver, so the bandwidth is audio-limited, but it seems that
DC operation would require rebiasing of the detector to not detect AM in the absence of the HFO note? 
BTW also, this is the only way I could think of, to make it usable on HF: to rebias the detector as a product detector.

>Looking for the multipin connector, chassis-mounted plug, that goes on the front of the RU series of receivers. 
Also, the line sockets that fits it but the chassis mount is the important bit, someone thought fit to remove the one on my RU-19 set.�
Thanks, Ben.�
