While I'm waiting for parts for my Motorola Bakelite set, I decided to throw this set up in the bench. I've been holding off on restoring it because it's missing it's speaker, but i finally feel like restoring it too. It uses an oddbal 14BP4 CRT. It's a 1950 set with an early small rectangular CRT. The CRT tests a little weak, but I think it's very usable. Can't wait to get started on it and hopefully find s speaker for it.

Here is s chassis view. It's also missing part of the flyback cover, so I may have to make one.

Even though it's rectangular screen-set it has a nice early look to it with that big mask with it's brass bezel. Nowadays it's my experience that with a little patience just about any part can be located. Good luck with it!

That CRT is the most common 14" rectangular tube out there. Practically every manufacturer used it. The 14Q and 14H are a little more rare.

Awesome set! If you don't mind me asking how much did you get it for?

I didn't pay much for it, maybe $15-20. I went to a craigslist ad that said they had old tvs for sale. It was an old tv repairman who recently passed away and his grandson was clearing out his house. I ended up buying 15-20 sets from him that weekend. He was very reasonable with his prices. I even retired a set he wanted to keep to remember his grandpa by. Below is some of the sets I got.

That's a very reasonable price. And that's a handsome collection I'd say!

I can't seem the get the CRT to completely light up. No matter how much I play with the ion trap or focus cool, it still on lights up the top half. Any thoughts?

Is the ion trap magnet actually good? I seem to remember encountering one where the magnet itself had cracked and most of it had fallen out.

The hv is only at 4-5k, so I'll start trying to figure out why it is low. Maybe the correct hv, around 10-11k will help this out.

It seems fine to me, I don't see any damage at all.

An raster like that is usually caused by the yoke not being pushed all the way up against the CRT.

Is the crt a 14BP4a? If it is you may not need an ion trap. Also make sure the focus coil is properly connected to the B+, check continuity of focus
coil.

All I can seem to get is this curved horizontal line. I can hear the station tuned into and flickering of this line. Is it possible my vertical output transformer is bad?

Forgot the picture...

Looks like your vertical deflection circuits aren't working. Instead of a full raster from top to bottom, you have the classic horizontal stripe.

Don't run it for long periods with that bright horizontal line, or it may burn a dark strip across your CRT.

Have you replaced any parts on this TV? If not, caps in the vertical seem like a good starting place.

Yes all caps, including the electrolytics, have been replaced. And I thought this was going to be an easy set...

This is the best I can get it. Any changing of the ion trap, yoke or focus coil only makes it worse or gives me a horizontal line. I'm confused on what's happening or where to look next....any thoughts here?

Check the resistance on the vertical output transformer and yoke.
