i already tried that, no good.
VERY THIN WIRE though
How often do these damn ' block osc transformers' go bad? And what could have made it go, age? Or did some putz burn it up?
The Sams mentions shorting the plate of the osc tube to ground as a test, in a ref in one waveform, that put all the power that would be going to the tube to gnd via that transformer winding, that can't be very good for it...
EDIT====
just a coincidence?
