I've been looking into this.
Apparently it's a lot more complex.
1. Couldn't be made at scale now due to regulations around the lead.
2. Seems like a lot of the knowledge is lost too.
I found a factory on alibaba who can manufacture Crts with new old stock tubes, but their minimum order quantity is 500 and who knows what the quality would be like.
Couldn't get them to do a "sample run" of 10 for me either
- mrob 4y agoWikipedia links a page from "Springer Handbook of Glass" [0], which shows a diagram of the typical construction of a CRT tube. The lead glass is only used for the sides and back, with barium+strontium glass used for the front. It looks like use of lead glass is only a cost optimization, and the whole thing could be made from barium+strontium glass. As there is no other technology that matches CRT latency and motion quality when used with fixed 60Hz content (e.g. most console/arcade games), it should be possible to sell new CRTs at high enough price to make this viable.
