This sad looking set has had a bad life . Must of had 40 Or more a day during its working life then in retirement it’s been stored in a wet or damp place. On top of that it was used as a parts set. I thought it should give it a second chance.
I replaced the missing dropper,frame output transformer and the main smoothing cap and a few other bits.
W8 the H.T. rectifier diode was shorted . I put in a 1N4007 to get it working. Can someone please advise if there is a better choice.
It powers up but takes ages for the raster to appear then it comes on instant to a full screen ish. I get a picture that’s fussy round the edges and a few black lines across the top of the screen.
CRT looks ok contrast and brightness wise.
Sound has bad hum when tuned to a signal.
Hopefully I can get some help to speed my progress up .
And I had the famous words said to . Oh last time it was used it worked.
I did laugh to myself Andy
