Right side retainer snapped off. Needs re-attachment.
AC power from leg
AC
power input on leg.
Antenna and ground connector on opposite rear leg.
New hindge.
Ugly but functional.
I found a loose wire under the chassis at the point of this burn. You
can see the wire fragment on the lower right of the chassis.
Clean!
That is the outer "spaghetti". The wire insulation is in
tact.
AC HV secondary.
Dodgy power switch may need
replaced.
#80 filament.
Filament string, no tubes installed.
Field coil connection to ground. Negative?!
B+ on another tube.
22v ac ripple on B+ no tubes. There was absolutely no hum at the end of
the DBT procedure (direct line power).
I find a DBT is more convenient than a Varriac and a meter
compliment.
Once populated with all tubes and
increasing the DBT wattage I plugged it directly in to the mains. It
sounded great. No hum. No arching on the burned 80
socket.
