Looking for schematic for Zenith K731 tube radio. Chassis 7K07 or 7M07 ( I
have both). The one on
http://techpreservation.dyndns.org/s...ics/Zenith.htm is useless because
it is blank/corrupted/whatever. It just does not display on Windows or OS
X. Yes I have the latest DJVU viewers on both. Other files from the
above link display OK, but some do not.
