:loser: When I was a teen, keeping in mind I never liked transistors, I devised, but, never developed my own idea for a solid state picture tube. It may not have worked, but, I drew a schematic at the time, and my boss at tv repair shop said it might work. I long since permanently lost schematic, and long since forgot all details, never to remember again. Yeh.. Probably wouldn't 'uve worked, anyhow....
