Default Re: Was 819 HDTV?

One of the 819 line television receivers I brought over from France last year is a compact 17" set made by by a firm called ITV.
This set will be ideal for conversion to a baseband monitor as it employs a fully isolated chassis, the mains transformer has proper isolated primary.
All the valves are 6.3 volt types, e.g. EL36, EY88, ECL82 etc.

The video output valve is an EL83 and 3 volts of video are required at the control grid for a fully contrasted picture. A video pre-amplifier will have to be constructed, I'll use transistors instead of valves as there is not much available space inside of the cabinet.

The set has a turret tuner but is only equiped with coils for channel 8A.
The IF amplifier uses three EF80s, one serves as a common vision and sound amplifier, the other two are in the vision IF amp. One EBF89 serves as the sound IF and detector.

The picures show the set and the special inverted magnet loudspeakers.
