My grandma had one with the same knob layout and swing open controls below the speaker, 25V picture tube, it was a 12B14C50 chassis.
It required few repairs and got lots of use in the first 12 years. The tuner was incredible for DX reception IIRC
I kept it going for another 7 but it became a bench-tech challenge, replacing electrolytics, varistors and other odd components.

Like a high performance car, these had odd symptoms and "special items" (thanks, Old Coot!) you had to watch out for to avoid disaster.
The crumbly plastic as noted above (thanks for the warning, Tim) is an age issue as much as heat issue.
