RCA Projection TV in Central Europe

[centurion]

My optical system has to spend a lot of time in the rust remover. The mirror absolutely requires a new coating. There is a lot of work.

Upgrading the EHT circuitry and semiconductor components can improve image quality, but I personally prefer to keep the old "spirit" of the device. It seems to me that yellow capacitors are enough of a novelty in a tube device. Today, the biggest problem with old TVs is probably the cathode ray tube. In my country, a few years ago, you could buy old picture tubes and valves from military warehouses from the 1960s. Today this is no longer possible. I have one Russian tube that can theoretically replace the original RCA one/5TP4/. If I successfully complete the renovation of the RCA, I will experiment with another CRT.

It will be nice to see the image on another 648PTK or RCA 9PC41
