Philco actually was acquired by Ford in 1961, but did not add the Ford logo until 1968 or so.
The Philco chassis that used the CTC15 clone was either a 15M91 or 16M91

This set is a working example of how sitting in a conditioned environment actually preserves the caps, pots, etc.

I have the Sylvania tube in my Magnavox, also.

The picture on that set really is looking great! Good work! Now, someday you can fix the cataracts on the tube you took out, and have a decent spare!

When Magnavox started building their own roundie chassis, they always seemed to use Sylvania CRT's. Most were rare earth phosphors. :thmbsp:

I recently picked up an identical but RCA-15 at an estate sale for $10 including a 1954 Admiral B&W console in perfect condition except for a cataract. They're out there. Picked up another Zenith 4B25 from a church rummage sale as described in "rectangular" for free 2 days ago. And I was late for both events!
