Cathode volts are Whacked!
The CRT cathode volts plunge down to 175 if the brightnes cont is advanced. The range is way too wide. In looking at the Sams I dont see a signal path for video between the Video amp and Video output. I"m sure it's a Sams oops. The Vid-out grid is way positive from what it should be at a normal setting of the brightness control. I think these two stages are likely direct coupled, but I want to make an educated guess before going further or pulling the chassis again. Any body have insight of a description of the circuit?
