Check the external wiring carefully: remember, the oscilloscope is
a vacuum tube device, it has high voltage windings and odd
requirements
for HV isolation of some of the windings. If you don't have a LOT
of data, rewinding it could be a disappointment.
Usually, a shorted winding gets hot; if it's really 'half volts'
that is the issue, look for a 110/220V selection switch.
