1960 Panasonic

[Dave A]

I got it! My first email is stuck in a network switch somewhere. The second worked this morning. I now have it at home for $90 untested. My thanks to our admin for finding this in my back yard.

The sellers were two old girls moving out. They are the original owners from 1965 or so as they remembered. They bought it in St. Louis and then to Denver and on to Valley Forge, PA where it went to the attic 33 years ago until today. They claimed it was the first Pana color sold in the states. I will let others decide. They also have the paperwork somewhere and will send it when they find it. 17" CRT marked as 490HB22. Cabinet is fine but for a few scratches I can fix. Clearly a tabletop for most markets and screw-in legs to make it a console.

Google does not help much other than a Life magazine ad from early 1967;

Same set but the tabletop version.

It is a Panasonic CT-66L which gives me a 1966 clue. The L is probably N. America. The Life ad from early 1967 fits. A trip home in the back seat of the 93 Caddy with the legs off was good. They helped me load it.

The chart shows two filament strings. The first glowed at 50v on the Variac. The second at 80v. Then I got a line at 100v and it stayed a line at 115v. V troubles somewhere. Service switch did its job. The line pic was for a few minutes to take the pic. The bright and contrast controls did their job. Moving the H control would bounce the line. Shut down after that and no damage. I will save the Beltron for later when I see a a picture. There is a cover under the cabinet for chassis service. The fly looks fine. On-off is shot. Line switch used for years.

The CRT is not a 21" type. More modern. The chassis pic shows a convergence coil leaning over. Very old damage and it still ohms out. I will leave it alone and secure it with glue. There are red and blue cutoff switches at the bottom on the convg panel. The line was fine to almost the edge of the screen. Tubes are too odd for my tester. May have to shotgun replacements and I will be back to you for replacements.

Tubes are mostly Matsushita with a few Sylvania replacements. Matsu shows codes of 6F and 6G. Not sure about that coding. The dipole is an aftermarket add-on and in perfect shape. Plastic bezel is a wonderful chemically degraded pale yellow.

Stay tuned.

I believe so, in this time frame IIRC, the number represented the exterior diagonal of the CRT bottle in mm, so 490 would be 19.29 inches... likely the screen display diagonal was about 18.5 inches.
Example: an early 12 inch Trinitron CRT was the 330ab22. 330 divided by 25.4 equals 12.99 inches... the screen display diagonal was slightly less than 12 inches.
