[ARC5] ARC-5 Question

[WA5CAB at cs.com]

Is it actually an "ARC-5" (i.e., R-23/ARC-5) or is really a BC-453-B?  Some 
(many?) late production BC-453-B's had the unused contacts not installed in 
the connector in the front box (and the connectors for the RF and IF 
coils).  However, the hole where the contact would have been will still be there.  
If that's the case, count the empty holes as pins.

PS - don't solder wires to the pins.  If someone later wants to plug in a 
control box (or on the rear of the receiver a dynamotor) it won't fit.  And 
the solder is next to impossible to remove, even with custom built vacuum 
pump equipped desoldering equipment.  Also, aside from building an ersatz local 
control box (originals are as scarce as honest Chicago politicians), the 
thing is plug and play.
