Just picked up from Chuck Azzilina a rather nice 10 inch National television set. He was most kind to part with it. Pics to follow. Thank you, Chuck.

I've already replaced just about all of the tubular caps. Waiting for some electrolytic Caps from Mouser. I'm tempted to bring it up with a variac and see if the high-voltage comes to life.

The mahogany cabinet is responding exceptionally well to a wet rubbing with Howard's, some 1000, 1500, and 2000 paper. Before the rubbing I filled in all minor imperfections with some 1960 formula DuPont furniture lacquer and an eyedropper. Result? Looks like an unmarred specimen with a fine patina shine. Vintage perfect.

I'm happy so far.

Like this?

Those seem to be scarcer than the 7-inch Nationals. Nice!

Yup. A bit rarer than the 7" TV.

Mine is missing one of the 4 x 6" loudspeakers. It's the one on the left as you face the front of the TV. It's a permanent magnet speaker, and it's part number is K-892-2.

If anyone has a junker chassis I'd appreciate a holler. I think the 7" National has the same speaker.

Is that the model with the two chassis bolted together?
A 4X6 PM speaker is rather common. If it's mounted to the chassis, with a special bracket, another way of mounting would have to done.
I had one of those sets 50+ years ago. Scrapped it!

Yes. One of those...

I know a pm speaker like that is common. Just want to try to get an origional, if possible. They are mounted to the cabinet.

Thanks

Just about finished with the recapping. I'm waiting on some caps from justradios to complete the job. Plus, the cabinet is coming out very nice. I've managed to resuscitate the original finish, which is always nice.

I'll try to post pics by the end of the week.

Here are some before pics of the twin chassis. As you can see they were rather rough. Quite a bit evidence of water and/or rodent urination corrosion to the chassis. But, careful disassembly, cleanup, and minimal spot spraying of a Rust-o-leum Copper paint over the worst spots/areas, carefully blended with the cleaned and lightly polished undamaged copper plating yielded a vintage looking chassis.

The after pics will follow.
