21-T639 Update: CHASSIS PULLED

[fujifrontier]

Had to grab the Raid and squirt a few scary-lookin spiders that had begun to call the RCA home, but I yanked the chassis after gingerly pulling the HV lead (and wrapped it in tape, to make myself feel safe :P)

As (Sandy, I think?) would say, she's a dirty old whore!


My first thought is, "What have I gotten myself into????!"


It does indeed use PC boards, but they're riveted on. How'mi supposta solder them new caps on? It seems that the RCA had work done, but why they didn't replace the other caps at the same time confuses me. There are also a cuppla orange drops on a small board on the top of the chassis.

Don't some of those have natural wax dripping, or do you think it might be bad?

To pull the front glass, would those clips be the ones to take out?

The pot on the far left turns, but doesn't move. I think it might have been pushed back... the others feel grainy and dirty when you turn them.

What would cause a spot like this in the HV tube? Age?

How do you re-wrap these canned tubes correctly when you put them back in? I unwrapped one out of curiousity, and I couldn't make it go back on correctly.

When I get the good camera later, I'll take some more pictures of it. I realise that in order to take on a project of this size I'm going to need a dedicated work area where I can have this chassis in one place... it's not like the Philco I can shove in a bookshelf and fume about.... Looking over this chassis has made me realise how little I know about TVs and electronics in general. I would like to -try- and work on it, but some of the questions I will have more than likely will cause some to wonder "do you even know what you're doing?"

Anyone have that schematic?
