Setchell Carlson...588 dial, 407 cab, 420 chassis(?) Serious need of a schematic.

Martin. There's very poor coverage of Servicing information in Riders for Setchell-Carlson. My 6volt tombstone farm radio isn't in there either. It's a real neat design using engineering I haven't seen before.
Your radio looks like it used three 25L6's instead of four.
