Superior Instrument Co - TV Cross-Bar Generator

[Tube TV]

I finally found a schematic for this so I thought I'd add it to Bob's thread. Now I can get mine going as well. My unit has never had a working bar oscillator.



Schematic and article was found in How to understand and use TV test instruments by Milton S. Kiver. Page 99 - 100

The schematic predates the use of a war surplus 7193 for the rectifer.
