1-125 Sylvania

[jeyurkon]

Thanks to RCA2000 I now have a model 1-125 12-1/2" table top Sylvania. Guess Sylvania includes the OD of the CRT in their sizing.

Jack was kind enough to deliver it to the ETF and Bob Dobush was kind enough to transport it to his house. I attended my dad's 100th birthday in Chardon, OH this weekend and stopped by Wellington to pick it up on my way back to Michigan. My brother is on the left in the photo and my dad's brother is on the right. Of course my dad is in the center.

The mahogany cabinet is in pretty good shape. I might try something like restor-a-finish. Or, just a good cleaning and waxing.

The set seems to have been in a very damp environment at some point in its life. The tube pins are quite corroded and there is rust on many parts.

The HV RF transformer seems to be good. I was afraid that it was damaged. The lead that goes to the anode cap of the 1B3 has been re-worked and appears to have been pulled loose and is just hanging by the secondary winding wire. The 6Y6's key was broken off. It looks like the HV section may have taken a hit and the 1B3 possibly broken yanking on that wire. Of course this is just a guess since the 1B3 isn't there. I do measure the proper resistance for the secondary so I'm happy. Someone has worked on this section in the past because all of the color coded leads to the transformer were replaced with yellow PVC wire.

The 12VP4 has marks on the aquadag that would have come from being in a CRT box. That will make it easy to remove. They glued the CRT's in when installed at the factory. They didn't ship the CRTs separately so this might be a replacement CRT. This CRT isn't covered by testers so I was going to set up a grid cutoff test using an external HV supply with a CRT tester like I did with the 10MP4. However, at this point I think I'll just pop it into my other Sylvania and see if it works. I fear that I'm too late to send it to Scotty if it needs rebuilding.

The bezel has some crazing. The crazing follows the flow of the injection molding.

This set will make it easier for me to make the front panel for the cabinet I'm restoring for the 1-128. I can use it as a template.

This set has the first chassis revision released after the initial design. That eliminates most of the serious issues with the original design. There are a number of revisions after this, but this one should be fine.

I need to get a can made to cover the HV section though. It makes horrendous RFI otherwise. Anyone know where I can get a custom can made?
