Here's a look at the chassis.


This thing is a real trip underneath. It does not use a flyback! The horizontal yoke windings are driven directly by a pair of 7A5 tubes.




The 7A5s are in the bottom left above that strange looking transformer.


The HV is generated by an RF supply similar to electrostatic sets.
