Randall RG 235 DS schematics ??

[nosaj]

I just picked up a randall RG 235 DS head and 2 stereo spks for $60 output seem audibly low. Looks to 1991ish by stickers on inside. Does anyone have a schematic for it?

Caps are first thing to be replaced but just wanted to check values as I see some mods in there.

Thanks,
