One thing to check on this radio is the rubber grommets used to insulate
the chassis from the case. They are usually dried out and need to be
replaced. Use an isolation transformer when servicing this radio. If the
grommets are bad there can be a direct connection to the case from the
AC line. I have a copy of the original manual, it's not great but I
could scan it.
