I had a set like that only 50 years ago. Mine had the handle that folded below the front bezzle. The set worked perfect and had UHF.
Yes, and a 3rd as well that was in the best condition of the three. I got that one running without much trouble.

As for this set, I found a fried resistor in the vertical circuit. I think it fried because I didn't install the focus strap correctly and put 245V across it.


I figured the focus (pin 6) could connect to either pin 2 or pin 10 (whichever gave the best focus) and had it going to pin 2.

However, the schematic shows it going to pin 10.


That got the vertical working better, but it was taking a long time for the oscillator to startup. I went to swap out the 8CM7 and discovered I had installed a 6CM7 by mistake


It's working much better now
