Ouch!!! There is no way you'll repair the original CRT if the glass is broken (or even cracked). Fortunately, there appear to be only 2 common flavours of monochrome CRT used in terminals/monitors. One type has a 8 pin B8H base (like an International Octal with thin pins and a large spigot), a thick neck, and a 6.3V heater. The other has a 'modified B7G base' (like a 7 pin miniature tube/valve, but with a hole in the middle of the socket to take the seal-off tube of the CRT), a thin neck and a 11-12V heater. Most such CRTs (of both flavours) have a 90 degree deflection angle. If you can get a suitable tube of the same class (perhaps raid it from an old terminal, like a VT3xx that's blown its flyback, or raid it from a cheap portable B/W TV), it's likely to work. You may have to fiddle the electrode voltages slightly, but in my experience, putting the CRT in, fitting the original yoke (these are _not_ generic), and pluging in the base and EHT cap will produce a useable image. -tony
