Either I'm nuts or this guy knows something that I don't. I started on the power supply filter caps for my RA-103. This TV had the big box cap (10mfd/600v) strapped to the top of the high voltage cage.
It looks like he took the two 80mfd filters, C262 and C241, out of circuit, along with the 100K resistors R316 & R317, and subbed this 10mfd cap.
In the photo, C241 is above C262. The long blue and red leads came from the box cap. So that cap was wired between the positive of C262 and negative of C241. The resistors are nowhere to be seen; perhaps they were originally mounted on the cans.
I'll put everything back as per the schematic, of course. Just wondering whether this scheme actually worked. That was a big honking (possibly nonpolarized?) cap in that box, despite the low capacitance value.
(Don't ask me to fire it up with that thing in place just to see what happens. The answer is No
)
