Re: Original Moulds found for Tek Scope Tubes
Fascinating! I’d never thought that CRT’s were moulded in ceramic but it makes sense. I’ve seen film of the making of valves which seem to use pre-formed glass tubes but I suppose precise display tubes needed different parameters. Perhaps ceramic is the only way to achieve perfection in ‘scope tubes?
There’s a YouTube of the process here: https://youtu.be/G0Dci5RPe94
