National TV 7w scratch one off the bucket list

Well unexpectedly this little National was found on another antique Radio forum I worked out a deal and now I'm the proud owner a little restoration here and there but it's definitely been one that's been on my bucket list for quite some time. Seems like you're straight forward restoration when the time comes anything I should look out for especially

Those are fun sets to work on, nothing very tricky. Here's an article about my TV-7W with restoration notes:

https://antiqueradio.org/NationalTV-7W.htm

The article points out a couple of small caps that you might not spot at first.

Besides standard recapping, I'd recommend checking all the resistors and micas in horizontal circuits.

Regards,

These are probably the very best of the 7 inch postwar sets. A great find!

More speaker area than screen area....Can you imagine if modern sets followed that design rule?

I've been Hawking your site for quite some time Phil one of the best sites I've seen for the electrostatic sets I originally wanted a national metal cabinet or one with the antenna tuning meter but then I decided I'd rather have the wood Case Model because it fits in better with my other sets and besides it doesn't look like a boat anchor... I can't wait to get started on this. The cabinet will be the biggest challenge Nedra veneering and I'm trying to save the entire front panel and keep it as much original as possible think it's going to be a fun little project. Banderson on YouTube also has a very nice restoration thread for the same set only in a mahogany cabinet.
As for the two hidden caps I'm glad you reminded me of those I remember them in bandersons video but most of all importantly my Firestone 13 G3 uses almost the same identical chassis and underneath the high-voltage cage there are some of those caps as well that I forgot to replace the first time LOL I won't make that mistake again took longer to take it apart the second time that did the first

Very nice set.
One model used the speaker space on the left for a signal strength meter... handy device for tv installers and perhaps hams/dxers. IIRC, all models brought out the AGC line as a back panel connection, likely for the same purpose.

Indeed, a very nice set
