1965 Westinghouse Attache Twelve NIB

I just wanted to take a minute and thank everyone for their kind responses. I've put a few hours on the set over the last few days and I love it. I have it hooked up to a generic Chinese ATSC/NTSC converter that includes a USB port on the front panel. Using this box with an antenna, the picture fills the entire screen. I can also rip video files onto a USB thumb drive and watch that way too. Unfortunately, there's a significant buzz that I can't seem to eliminate. Any suggestions would be welcomed.

When I have more time, I'm going to dive deeper into the set and see if I can find any more markings that would clue me in to the manufacturer. I agree that it's probably Mitsubishi.

And Dieseljeep, I'm going with 1944.

You are so right, regarding my year of birth, December, 1944. Franklin Roosevelt was the President.

Never seen one witha USB port before, Sounds like an interesting converter box.

Here's an example of one that happens to be on sale for $39 at MCM:

In addition to the USB port, it also has component outputs so the Green or "Y" channel could be used to feed a modulator and avoid the chroma dots on a vintage B&W set.

Edit: It looks like the URL I posted is too long, and just takes you to the MCM site. Search for "High Definition Digital Tuner with HDMI and Component Video Output MCM Part #: 30-2890 | Stellar Labs Part #: DT-800"

As much as I love all things Westinghouse, I would hope on some level that the Metuchen plant (1954-1970) produced yet another interesting design, but I guess they knew when to outsource such a neat little set.

Does that buzz get worse when there are bright white areas on the screen? If so, what is likely happening is that the set's IF strip is going into cutoff when the video carrier is at its lowest level (which happens at peak white). And maybe a tube, or some biasing circuit, is clipping the IF signal so it goes completely away. And in intercarrier sets, where the video IF beats against the sound IF at the video detector to get the 4.5MHz sound subcarrier. But if the video carrier disappears momentarily, the sound subcarrier also disappears. Which makes "holes" in the sound, thus the buzz.

One workaround is to reduce the amplitude of the video signal going into the RF modulator inside your ATSC converter box. This would allow a larger amount of carrier signal to be produced on peak white, and hopefully enough of the carrier reaches the set's video detector to avoid the holes in the sound subcarrier.

Or dig into the set's IF strip circuits.
