I've had several of those as well. They really weren't high performance.
Very minimal AGC. You always had to readjust the contrast, when switching from low to high band channels. The local distance switch was a joke. It stayed in the distance position all the time.
The later production sets were a little better, as the horizontal AFC was troublesome in the early sets.

What attention to quality there was back then...looks like a very labor-intensive process(not to mention all of the precious materials required)..all to produce a mediocre set I once found a Hotpoint-brand 50s tv at the curb and it had boards that looked just like this. It had sound and tuner but no video after the detector. I recall trying to probe the circuitry and the traces were beginning to lift. It appeared to be a victim of "running as hot as an oven"...tubes on pcb's is rarely a good build!
