Are you saying that the parasitic choke got hot enough to melt solder? Safe bet the tube(s) are bad.

Gary & Group,
More info-
Suspecting that I slagged my finals, I looked in the cage.
Saw a fresh solder blob near the base of the choke and a lead popped out from one of the parasitic choke resistors.
Looks like I'll need parasitic chokes (my hands can't make my own) and a pair of finals to substitute?
Suggestions welcome

Gary-
About 50mA, keying in CW mode.
In Tune mode, about 90-100mA.
Do you get idle plate current when you key the radio?

Gary-
Using an AC4-R supply.
PA plate, plate, filament, dial light and bias voltages are getting to the T4XC.
Dead driver or finals?
There was a reason the power supply fuse popped. Check voltages there first.

Group,
I'd welcome any advice on where to start looking.??
The 5A fuse on the AC4 blew in my absence.
Replaced the fuse, and cannot get a peak greater than 0.1A when switching from SSB to tune, regardless of the gain setting on 80 and 40.??
D'oh.....? ??
