[Milsurplus] Rectifier Module, ahoy!

Dennis, Chris, Bill, et al,

I have a very poor condition TM 11-1306, the only thing aside from the RA-38 
IB's, that I seem to have on the SCR-268.  Title is "Technical Operations 
Manual for Radio Sets SCR-268, SCR-268-B, SCR-268-C and Radio Sets SCR-516, 
SCR-516-C, SCR-516-D and SCR-516-E.  Subtitle is "General Description, Operating 
Instructions and Equipment Performance Logs".

A footnote to the Table of Component Parts says that BC-677 (and other 
related items) may be used in stead of BC-407-A (and other related items).  Nothing 
in the manual about internal details of anything except for a note that says 
that the BC-677 and related items use 13 tubes versus the BC-407-A and related 
items that used 37 tubes.

One other note says that SCR-516 and SCR-516-C are converted SCR-268 and 
SCR-516-D and SCR-516-E are converted SCR-268-B.  The first SCR-516-(*) in each 
pair was converted by the manufacturer and the second was converted in the field 
with conversion kits.  Not much indication of what the conversions consisted 
of although an operating frequency change appears to have been one change.
