Subject: [ARC5] Answering Floyd's Question

In answer to Floyd's question on bench testing 
command receivers, here is what I would suggest. 
 
First, since Floyd was talking about control and audio, 
I assume he already has power into the receiver. 
 
I would use a stock FT-230, and leave the pot, switch 
and audio connections external to the receiver, using 
the 7 pin rear panel connector. 
 
But that means finding the male plug for that connector. 
The 7 pin plugs from the racks sometimes show up, but here 
is an alternative. 
 
If you have a beat up, unrestorable, unrepairable set, pry 
an IF can plug out of the receiver chassis. It will fit the 
rear panel connector. The only problem is that pin #7, or 
center pin is missing. This pin is B+. If B+ is brought 
into the dynamotor plug, or you are running the receiver off 
the dynamotor, then this is no problem. You now 
have all the handles for gain, CM/MCW, and audio. 
 
It might be possible to add a center pin, by cannabalizing 
another plug, then you could bring power and control on 
one plug. 
 
Actually, if B+ and filament are brought into the dynamotor 
connector, then you wouldn't need anything 
plugged into the front of the receiver.
