Hello stevem,

already ordered the schematics.
No fuses dead.
Both PT and OT are fine.
Humdinger resistors literaly disappeared and left a black area.
Funny is Tubes are still heating.
10R Kathode resistors are gone on two tubes.

I expect only minor damages but I have to check those driver bjts.
One connector is missing. Wires were soldered on.

I have to order some parts and a set of 6L6.
Unit is set up for 220V mains,
will set up for 240V and then check heater voltage.
HT unloaded was 527V DC, 383 AC @233V mains

Will need some days for Progress.
Thanks for your Support.
