I've sent you schematic and chassis layout information on Allied 5H570. It was in Rider Vol #22 which isn't a very common volume.

: I just acquired a small bakelite Knight five tuber. There were no tubes in it, no model number, nothing. I think it's a model 5H-570 as it has a diagonally divided front panel. Does anyone have a schematic or the tube line up? I couldn't find the model number in Riders or Sams. Thanks.
