One side of filament is ground. Filament power comes from FBT through 1 ohm
resistor RL12 to filament.. Filament voltage from FBT goes to x-ray circuit.
Voltage at filament also goes through 680 ohm resistor RC08 to several other
circuits.

> I know 'no filament' is oversimplifying. Unit has HV, sound and vertical.
Everything including video amps are operating like everything is fine, but
no raster. Had good video once for 10minutes or so, then went out. Tried to
be clever and floated the heater pins and did the wrap around the fly core.I
had 1/4 screen but smeary at that. Changed the fly, but nothing. Checked
continuity from the fly out and it's good. Of course no prints so could use
a pointer or maybe a scan of the sweep circuit. Man I hate these. Any help
appreciated. Thanks.
