[NLRS] Accessory 'jack' for TE Brick Amps

[John (JK) Kalenowsky, K9JK]

Good Morning all,

I can confirm that the Accessory Jack for teh TE Systems IS a 7-pin 
miniature tube socket as were common in the days that radios "glowed".

The mating plugs have always been hard to find (even hardER these 
days) and often NOT included when an amp is sold since they get lost 
or have been bundled in to custom made cables by the seller/previous 
owner. And, they are NOT very "robust" as Chris noted.

I actually spoke with Dave (TE Systems' principal) at Dayton a few 
years ago (we ended up at the same table at the Friday Night Weak 
Signal Dinner). I suggested a change to mini-DIN for the accessory 
jack (specifically 8-pin, since cables with nicely molded plug 
assemblies were readily available in that configuration) and that 
PowerPole type connectors would be a nice replacement for 
"Cinch-Jones" power connectors.

The "official" Cinch-Jones 'number' for the Power Connector is 
"S304CCT" for the female 4-pin connector with cover and strain relief. 
I've also seen it referred to as "JCJ4F". That may give you some terms 
to Google (or insert YOUR preferred web search engine here). 
Unfortunately, I don't have any 'numbers' to try for the 7-pin 
miniature plug.
