Chassis Notes(most schematics can be clicked to download a full size version)

The 58's were noted by a previous serviceman (who left a note in the cabinet) as being PH58's (Philips manufactured equivalent of the American 58), and the Wunderlich is presumed to be correct, as it is noted as an unknown blue valve (Arcturus manufactured Wunderlich valves which were used in the first audio position around this era).
