I'd connect the ground to the ground pin on the filter cap? Please bear with my pure stupidity here please.

the can is a multi section cap with a common ground. IF the can connected to the chassis then you would connect the neg lead of the 50u cap to ANY place on the chassis. IF the can was not grounded then you would connect the neg lead to the can itself. In this case IF you are looking at the right can (C104) and the right section (B) then you would disconnect any thing connected to the "B" section and and then connect those wires resistors what ever you just disconnected to a pos lead of a 50uf and the neg lead of said 50uf to what ever the can was connected to, IF you are on the right can it would be the chassis.

maybe you should take a hi res pic of what you are doing.

this is all just a temp thing to see if that can is bad (or that section anyway).

just tack it on and make sure nothing shorts out, go a quick power us and see if the 270v come back.

If it does then that section is bad, and the whole can should be restuffed.

all of this would not be needed if

you had the proper cap tester OR

just went ahead and restuffed. I prefer to test but if you dont have the correct equipment your options are limited.

If I were to restuff it could I use a 56 uf instead of 50?

[DaveWM]

typical

82 for 80
56 for 50
33 for 30
27 for 20


remember the orig caps were +100/-50 tolerance.

dont for get to get the 4uf (use a 4.7) in on the video pcb.
