Cathodes/ rebuild?

[dtryon]

Greetings,
I see this post is old but I'm a new member so it's new to me. Was any progress made with sending a tube to EMI for rebuild ? Seems like the subject just got dropped. Maybe it's in another post? Any Info?

Thanks,

Dennis

It was an EMI tube, potentially to be rebuilt in the US. The EMI company as it now exists has nothing to do with this. AFAIK the project didn't get any further.

Jeffrey,
Thanks for sending me to your article. It was very interesting. I love reading about all the dedicated people trying to save our hobby as well as save the history of television. It's a shame so much has already slipped away. At least it seems to me that the more people interested, the more hope their is of preserving the history. It's a frustrating fact that as each day goes by someone cleans out a basement or garage and not knowing the value, throws out and or destroys another piece of history. Everyday we lose a bit more. I'm glad at least a few of us are trying to save a small piece of the past.

Thanks again,
Dennis

Any idea if that jug is still working? Just curious if it held vacuum and such.

It's probably fine but unlikely to be run in the near future. The set is in the reserve collection at the National Media Museum, Bradford, in the north of England.

Pity they don't run it once in a while. Sort of pointless to rebuild one and then never use it. I understand limiting the hours of course but still.

This is part of the usual musuem question of preservation versus conservation and restoration. It's a big subject in the whole world of museum keeping. You can argue it in various ways and there will be no fully satisfactory conclusions.
