Sir roughshawd . . . . .
( My Spell Check is now cocking its head and questioning your spell competency of your user name ? )
It has a transformer that induced 35v 12v 5v and 12.6v
To be more exact . . . . .amend that to be outputted DC supply voltages of +35 -35 +12 -12 and +5 .
Now some questions . . . . is this being your own unit from its day one and are you well acquainted with the unit in the interim ?
Can the lightning strike be pinpointed . . . . with other household items receiving damage . . . . as coinciding time related to the Gulb death?
Or is there a possibility of the unit being left turned on . . . . . forgotten . . . . . .heating up . . . .and transformer being damaged by shorted power supply diode(s)sets / bridges ?
Now is the time to test the D9 and D10 full wave rectifier set.
Move on, to then test the D1-2-3-4 full wave bridge rectifier build up.
Move on, to then test the D5-6-7-8 full wave bridge rectifier build up.
They may all need to be out of circuit , with one lead floating free. . .to be sure.
If no shorted junctions are found . . . . the lightning hit might be valid.
IF bad diodes were found you might then leave them in that / their disconnected state and test the transformer with power applied, to see if smoke /or/ any stinkee-poo emanates.
Then if a transformer need is confirmed . . . . . . study the schematic below to see if it is being in agreement with your unit.
Also . . . . in the past good times when playing this unit . . . . .what was the volume level setting normally played at . . . . 25% 50% 75% . . .?
Also, doesn't this unit use 8 and 15 in spkrs ?
GULB POWER SUPPLY . . . . .

Senility has been a quite smooth life transition for me.
