Restoration Project #1 1950 GE 16C116

[ketron281989]

Hi guys, I am a new guy to the forum, but a novice to the hobby, I have quite a few radios, and this year, started with the tv's. You are welcome to check out my gallery as I have posted pictures of all the sets I currently own.

Anyhow, I wanted to let you know that I have started on my first TV restoration which is this GE. It is in pretty good shape, I know there was a servicing in 1960 with the addition of a new Philco CRT, just about all Philco tube replacements. The cabinet is in pretty good shape, speaker great, cloth is also very good. I just finished cleaning the chassis, pictures below, I have a B+K CRT tester that I am still figuring how to operate, I have never tested a picture tube before, but I have tested many radio tubes with my Model 68 NRI.

I just wanted to introduce my project and a few pictures, very soon I will have more questions, probably later today as I collect my goals for this set.

Let me know what you think and if you see anything out of the ordinary on the chassis. I appreciate all of you're guidance in completing this restoration which I hope to have done in the coming month, then on to my other sets.

Thanks, Happy New Year

Jon

You'll need to address the hot chassis issue this model has. This uses a B- with a resistor tied to chassis ground.

Since it has a hot chassis, does that mean it is transformer-less, There are three transformers underneath. Will I need to use an isolation transformer?

[leadlike]

The three transformers underneath appear to be a choke, audio output and vertical output transformers. None of these things do anything to isolate you from a nasty shock.

Well I will be sure to get an isolation transformer, thanks for the help, is there a way to test each of those transformers. I will be getting the SAMS photo fact in the mail here in a week or two.

[Phil Nelson]

Testing transformers is usually a low priority for me, since almost all of them have been good (knock on wood) in the TVs I have restored.

Sometimes a schematic will indicate the resistance you should expect to find on the various transformer windings. So, you can check that resistance if you like, being aware that any components connected in parallel may lower the resistance.

As with tube radios, the biggest single task in restoring an old TV is replacing capacitors, starting with the electrolytics in the power supply. The restoration section in my website has a number of TV articles that will give you a general idea what's involved in fixing these TVs.

Cool thanks Phil, I will check that site out, I have looked at your radio stuff, but will be sure to check out the TV section. Thanks
