ANTIQUE AMP SCHEMATIC

N

Hi all...
I'm looking for the schematic for an old movie theater amp...its a small RCA MI- 4236-A P1185 SER
VOLTAGE AMPLIFIER UNIT. I believe it may have been either their standby unit or maybe the amp for the highs. Can't seem to find schematic. I know it takes tubes # 56 & 57 but the other's a mystery.
Also I''m trying to clean it up & took a wire wheel to the top of it down to the bare copper because the grey finish has started rusting. Should I leave it that way or repaint it or maybe clear coat it? Thanks!!!
