In the schematic clip you'll notice the only dc path is thru the brightness control that has 275 v and ground. The wiper goes thru a 180k resistor to the cathodes. The signal path is thru a .5uf cap. In a perfect Sams world the cathode potential should vary and at some point give raster. The reality is, the set doesn't follow Sams. One end of the bright cont has never had a connection soldered to it, spurring on my suspicion the schematic is not correct. Thats why Im hopeing for a better schematic or bulletin.
