Had a check, C4520 in mine was a 33uF cap, I checked the capacitor and it seemed way out of value, so I've ordered some. Hopefully this cures the sync fault, we'll soon find out.
As I say, mine was 33uF, so I checked my circuit diagram I have which also said 33uF. Just wondering why they'd be different in our sets? Could it be the VCR modification?
checked the 205V rail, it's at 191V on the dot. This isn't too low is it? I know some people run them at 195V but it seems to be working just fine at 191V. Not an issue to raise it to 195V if need be.
Thanks for the help
