Real progress on my RCA 630TS!

[Jonathan]

Thanks Phil for the reply. I always enjoy looking at your site, and you did a great restoration, not only the 630TS but your other radios and TVs as well. I have some very expensive Ecoline Contact Cleaner from Techspray, and it usually does a great job with pots and contacts. I'll be getting some DeOxit too. It's a few dollars cheaper, but probably just as good.

When initially recapping this chassis, I removed all electrolytics and saved them. I should have restuffed them, but I was stupid. I reduced the total amount of electrolytics by using a 120uF 450V instead of a C221B 40uF and C222A 80uF in parallel and an 80uF instead of the two C221A and C220A 40uF in parallel. I used terminal strips to mount the new electrolytics. It looks very messy, but I tried to fit everything underneath. The underside of this chassis is very messy-looking anyway, so I guess it kind of blends in. I also removed the power transformer and used heat shrink on all of the broken and cracked wires, thinking there was a short causing the problem and not the electrolytic I put in the wrong way. I put labels on all of the wires before I removed it.

Also, the power switch is kind of funny. During the "off" position, the contacts are closed, but should be open. Dirung the "on" position, they are open. This was a couple years ago when I last was working on the chassis, I never retested it since then. I have the AC directly connected to the power transformer for now. I know I sprayed the hell out of the switch and the switch worked as normal, but once it dried, it went back to being funny. Eventually I will fix this.

In the mean time I'll clean the tuner, pots, tube pins and sockets as you said, plus I'll be using naval jelly and metal polish to shine up the chassis.

Attached are pictures of the underside of the chassis with new capacitors installed. I replaced the electrolytics, the paper, one black beauty paper, and the rectangle mica, as well as the AC line filter capacitors.
