Hey David, I noticed something different between your chassis and mine.
Mine uses a large multi section resistor riveted to the top of the chassis and yours doesn't. Yours also has channel one, my chassis seems to be wired for channel one but it's been cut short and there's no hole for it in the cabinet.
Guess I could drill a hole in the cabinet and make a "Rare" channel 1 505.
I know yours is a T-54 and mine is a 505 but I thought they used the same chassis? I imagine mine is later since it's minus channel one. I know the really early ones used Octal tubes in the i.f. strip.
It also looks like that decal I so laboriously restored is different on yours also.
