Schematic for early Hallicrafters -54

[Ralph S]

Hi All!

Does anyone here have a schematic for the early 13 channel version of a Hallicrafters T-54 which uses 6SH7s for the Video IFs, audio IF and 1st video? There are other parts differences between this version and the one in the Sams Photofacts dated 4-50, Set 91, Folder 6 which uses 6AU6s in these positions and is a 12 channel set. I need to double check parts and wiring against a known, correct version given that I don't trust what I'm seeing on the set I've recently bought. It looks like it was worked over years ago by a real hack!

Help!
