porthole flyback shorted - any replacements ?

[kramden66]

kvflyer good luck with it , the amount of capacitors is nothing compared to some dumonts and rca sets , beware of mica looking or micamold caps that are really paper/wax type values like .001 , one i missed in my set caused the whole vertical to not work.

Eric where do they sell that stuff ? wont hurt to apply it maybe it will cure it .

btw those pics show the set not totaly adjusted as far as vert and horz and the contrast is up all the way , shows that the crt had better days but watchable with a brightner , without it the image slowly gets a little darker and less blacks or if started up from being cooled off its just darker and less blacks.

I would replace that 10 amp fuse with what ever is noted in the schematic or on the chassis. Usually a 0.25 amp type.

The 10 amp fuse could cause a fire and that would not be a good thing at all.

Your pictures look keystoned, so you likely have shorted windings in your yoke.

Looks more like perspective effect from the camera angle.

yes odd angles , it is laying on its side and difficult to take pics head on
