I recently acquired an RV75 to use in my 7-line station. The RV75 requires a cable from the RIT SWITCH phono connector on the rear panel to the ACCESSORIES connector on the rear panel of the TR7. This cable and CJ "adapter plug" wre not included in my purchase. Looking for the correct CJ part number for a plug compatible with the TR7 ACCESSORIES" connector in order to make the cable/adapter.

Thanks,

Jones plug nomenclature on the web suggests P-3312-CCT.

However, you only need this if you actually want to use RIT. The RV75 works just fine without it an honestly I have never missed it because I rarely use RIT anyway.

Thanks, Jim. Yes, I am aware the RV75 will work without the RIT cable but curiosity has the best of me and it appears to be an easy task.

Cinch Jones 300-series plugs


Drake TR-7 transceiver (Rear Panel) has an 8-position Cinch Jones connector (308) for RV-7.


The Accessories connector is a Jones 12-position connector (312).
==
Jones P-308-AB Plug is no longer being manufactured by Cinch (Obsolete),
so requires looking thru distributor/surplus house inventory and maybe Beau/Molex offerings.

Surplus Sales has this plug and proper backshell/hood to create that part (~ $10.50)
You might need to fabricate locking pin for hood.

Greg,

Thanks for your detaioled reply. I did find what looks like to correct connector on eBay.
