The main thing is to be patient.
I think that it seems that your resistor R9 may be connected incorrectly.
Unplug the radio and remove the 35W4 if you wish. It should not matter.
Measure the resistance from pin 7 of the 35W4 to the common rail. Pins 2 or 6 of the 12AT6 would be a good point for the negative rail.
The resistance should be infinite after a few moments when the 2 caps in C16 discharge.
If my guess is correct it will probably be low.
I suspect that one end of R9 may be connected to the common rail.
In that case the current thru the 35W4 will be excessive.
Good luck
