Is this a hot chassis set? I see a selenium rectifier, and no power transformer.

Yes, one side of the power line goes to ground.

WARNING: Unless you enjoy the feeling of a 60hz handshake, I'd recommend using an isolation transformer when working on, or even using this set. It has a hot chassis, connected directly to one side of the mains.

Saturday was a big mail day for this project, thanks guys! I not only got a Sams but a Rider as well...all much appreciated.
There are a ton of screws keeping me from removing the TV from the cabinet. As I remove a screw I tape it down to a sheet of paper and make a note as to where it came from. I'm doing my best to make this easy to put back together when the time comes. When I feel like I've got them separated I may have to call over a buddy to help, I imagine it being very front heavy. I took out a few tubes to get a good look at them and noticed the RCA logo wiped right off so I didn't touch any more after that, which was before the I got the schematics. I've attached a photo of the decoloration of the front speaker cover. After looking at the cloth so faded for so long it will be different to see this cabinet and speaker cover way darker. If anyone's got some cloth like this or has seen any, shoot me a head's up!!! It's hard to tell by the photo but the gold strands are weaved into the fabric. I was really tempted to drive the cabinet to Jim Obermeyer this weekend but Murphy's Law told me to hold off and see if I could get the TV to work first. |

Ok guys, I have one other quick question. I'm looking at this Rider schematic and it has a list of replacement parts. I've gone down the list of capacitors and made a note of all the paper ones. They range in voltage from 200-1000v. There is a stock number as well as a symbol number. Can I get all of these from www.justradios.com and is that the best place to go for these? I guess I want to make sure I'm getting the right things before I place an order. There are about 30 capacitors on this list.

Justradios is a great place to do business with but so is Radio Daze in New York. Most of the caps can be replaced with the 630 volt ones except for the 1000 volt ones. There you will probably have to go with 1600 volt caps. The 200 volt caos can be replaced with 630 volt caps. The actual values should be close, i.e., you can use a .047 in place of a .05 and vice versa.

Steve, thanks again! I'll get an order together and continue on.
