Looking for CRT type 130BUB31 data.
I'm repairing a 70's scope with this tube. Except for it apparently
having been made by Hitachi, web searches haven't turned up anything useful. TIA - YD. -- |

You didn't say if it was round, square or rectangular. I saw some Hitachi CRTs in later model Heathkit scopes, but I don't know if they were originals. They looked to be a Japanese version of a 5UP31 -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge. |

They looked to be a Japanese version of a 5UP31 Thanks. The scope's a Brazilian LABO 4521, not likely you've ever come across one. I have the schematics, just wanted to know a bit more about the CRT. - YD. -- |
