Yeah, the RS and RM series are electrically the same however, the schematics
vary depending upon the year of print. I have the RS-50M schematic from 2000
off the RB website. I requested a schematic from the rocket scientists at
Astron. What they sent is dated 1996 and the two have significant differences
between them not to mention a third I found elsewhere dated 1997 (again, some
differences). I wouldn't be so concerned except the differences are in
component ID's and values. I'm hoping someone has a more recent copy
available-- perhaps two out of three (or four) will agree. The protective SCR
is shorted in mine. I can buy the part from Astron next week but I was hoping
to find it via Newark, Mouser, or the like. The SCR part number varies
depending upon what schematic you look at but most call for a "SO565J". I have
not yet found the manufacturer of this part number nor a source outside of
Astron.
