Estaban, has your CRT been modified with A/V jacks???
I had a working vintage 1950's RCA B/W TV. I played consoles/DVD/VCR via RF. It was a blast while it lasted, but it eventually broke:
NOTE: I have an earlier, BW model, but it looks very similar to this later model.FATEFUL: I pulled out the huge mono speaker from the TV cabinet and installed stereo speakers in its place. The subwoofer, which is huge, can be hidden underneath/behind the cabinet. The vacuum tubes for the old CRT were expensive to replace, so I made the painful decision (a few years ago), to replace the B/W convex CRT (which was nearly an oval in shape) with a "modern" color set. A 19" television was the biggest size screen I could fit in the cabinet.
I'll take pictures again one of these days...
