Cathodes/ rebuild?
 
Stumbled across this by accident. Ever heard of this Co. before?

Interesting reading about the company's activities from the site.

Well found. They certainly have some unique capabilities. I have just emailed the company from the UK.

Note the copyright 2005 on the pages. Makes me wonder if this place is still in existence.

ppppenguin 08-01-2013 02:36 AM

They are. I've received an initial and reasonably positive reply to my enquiry.

I've had a positive response from the company and am now seeking somebody to volunteer a pre-war EMI CRT for rebuilding. Other early Pyrex CRTs might also be relevant - I don't know what types were then used in the USA.

Cost would be $1000 + shipping both ways. Work would be done as a best effort. Obviously success cannot be gauranteed.

Because of the risk it would be best if a totally dead CRT was used.

Any update on getting a volunteer CRT for rebuild?

ppppenguin 09-11-2013 01:47 PM

Yes, we have a volunteer. I will let them post their identity if they wish.

Very interesting company. [edit] I just read the company profile. Figured they had to have been somehow associated with the old Tektronix.

Any Progress or Results ?
 
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?:thmbsp:

Thanks,

Dennis

@dtryon

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.

You might like to read my 1987 article on the last known rebuild of a pre-war EMI tube: http://www.borinsky.plus.com/vintage_tube.html

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.
