I purchased the fisher model tv3 projection set at the auction in Dedham. Does anyone have information on this set? Its not in riders or the sams at all. Did someone else make the chassis? Any ideas would help please

Well a picture would help! got any?

never tried downloading pictures on this forum will try

I think it looks similar to a SCOTT 6T11 projection set.

Didn't they use the Philips Protelgram system?

Neither cabinet, layout, or chassis looks like my Scott 6T11.
The projection system is Norelco Protelgram.
Looks like series ballast in pics.

I think Im screwed on a diagram to work on it. Someone had to make the chassis? WHO?

Just a wild guess but I'd bet the Protelgram parts are similar to any set that uses them, Scott, Duo-View, Hallicrafters?

The crt and yoke are not the issue. Its the tv electronics are the problem. Cannot trace circuits or the tube layout. Its like no map no trip.

To my knowledge the early Protelgram came in 3 focal lengths but otherwise
they are basically the same. I have seen some later hv units using 1B3s
[not in this one].
