[Milsurplus] Remler Model MCG or AN/SIA-4 1-MC Amplifier Info

[Konrad Werzner]

Hopefully not too OT, but I picked up a preamplifier and audio amplifier
that appears to be part of a MCG or maybe a AN/SIA-4 1MC system. It has an
acceptance date of 1944 for the Navy and is listed as part of the MCG
system, synonymous with 1MC/17MC related communications circuits. Don't
have the full rack unfortunately, just one of the main power amplifiers
with 4X 811A tubes and the voltage amplifier "preamp". Thanks to Nick's
website for brief info about the set:

I haven't been able to find much info on it elsewhere. I purchased a RCA
Navy manual for an MCG of similar vintage, but the tubes did not lineup
with the tubes of my Remler. Any schematic tips? Any museum ships missing
pieces of their MC, specifically this one?
