Set off

Remove the horz out tube from the socket.

disconnect the plate lead from the tube.

put a DC volt meter on the plate lead (+) and the neg to chassis.

Set on should be about 400vdc

First time I got only 17 volts then all my other attempts were zero

ok now just trace back until you find the 400v

look for burned coils if nothing at the pin 5 of the damper

also make sure you still have B+, if the damper was shorted you may have blown the B+ fuse again.

use the correct fueses.

[DaveWM]

There is a power supply fuse that I mentioned that is blown and I am guessing that MAY be the problem..
