Interesting, thanks for the info.

I called JVC and they sent me the complete service manual with schematics, exploded views, circuit boards and parts list. The set has 7 circuit boards, 43 IC's. I see a video processor, micro controller, video decoder and ASIC scan field converter 1X to 3 X. There must be tremendous switching going on and a built in fan activates when I switch on the power.

This set retailed for far less then the Textronic. I got it for a song. Don't think the seller new what he had or thought it was an antiquated.

But remember, the Tektronix application was very high performance digital oscilloscopes (BIG$$$) not television monitors.... Here is one on the 'bay:
