Designs we love to hate!

Not the prettiest method, but it worked fine and it's hidden, facing the back of the CRT.

My father hated Emerson radio sets, they used to bury some parts under other parts, and you'd have to remove the top layer to replace something underneath.

I used to recap the vertical circuit in those RCA's, even when they were newer. There wasn't that many leads that had to be disconnected to gain access to the foil side. There was several caps, that had to be replaced.
The cap across the horizontal sine wave coil, .01 mfd @ 600v could be replaced, by reaching through the chassis holes.
The set pictured, is it a KCS108???. Don't let the chassis slip off the bottom rail, there goes the neck.

Mitsubishi and the fish oil caps! Once you smell the tell tale smell, get ready to buy a new tip for the soldering station! Surface mount microscopic resistors! The GE "swiss cheese" chassis! As bad as the RCA! Panasonic's "Prism" that blasted the neck of of it's CRT like Zenith with bad safety cap and on the same set, the inability to get the board out to repair vertical IC connections! Funai VCR that requires you to unsolder those wonderful wiring harness' to get the transport off the board! Transistors and IC's that have the part number removed at the time of manufacture! And don't forget the Sony TV with the double foiled mother board and daughter boards that were SOLDERED in! Removing the daughter boards always resulted in broken traces that took forever to repair!

It's this set
I don't remember what the chassis number is, too lazy to walk across the room and pull the back off...

Doggone. I dint mean to sound unkind toward that RCA. It was sed from the servicing perspective back in the day. If a shop didn't have a test tube or extension cables, there was no way to effectively troubleshoot (we did have those items BTW).
We got a few of those RCAs as trade-ins and somebody had literally cut and peeled back the sheet metal to get at the foil side of the boards.
From the design perspective, it was a "What were they thinking?" kind of deal.

I was actually able to recap my vertical chassis RCA by soldering through those holes on the back chassis side. Slow and painful, but doable. You need a pencil iron, not a gun, and a very good movable light source.
