[ARC5] ARC-5 or SCR-274-N ID Question

[WA5CAB at cs.com]

To answer an earlier question, the RF coil racks have the same A.R.C. 
number (6220) in both the 46104 and the R-25.  As do the BFO transformers (5854). 
 But the IF transformers are different.  

1st IF   7271   9681
2nd IF   7272   9684
3rd IF   7273   ?   (missing from manual)

Pin 8 on the 2nd IF Amp socket is grounded in the R-25 and not in the 
46104.  And pin 4 on the front panel plug is unused in the R-25 and has a wire on 
it (TEL.) in the 46104.
