Chassis works, kinda.
Powered it up tonight, first through a big bulb then full power with an ammeter in the line, draws about 1.9 amps.
I was concerned about burning a line in the screen if the set had no vertical sweep so I fired it up with the controls all turned down.
With the old CRT I got a dim horizontal line, and as I figured, no vertical sweep, the brightness control had no effect one way or the other but at least I know the chassis is functional.
With the new? CRT I had nothing at all on the screen, till I switched the set off then it lit up brilliantly, so much so I was afraid it would damage the tube! (the old tube does pretty much nothing when switched off, it also has a really burnt screen so I would guess it's about used up)
I decided to try again and by playing with the brightness I can get a line to flash across the screen for a second or so.
I 'm guessing the new tube is good but the much higher emissions may be dragging down the tired chassis.
I seem to also recall reading somewhere that some projection sets would cut the beam off if the sweep stopped working?? can anyone verify that?
