Hi,
Someone is regularly selling CD's on eBay with some potentially useful
information:
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=535115318&ed=978660813
I bought that one for $10.95, as much as I think he has a bit of a cheek
selling material he has probably got for nothing. Anyway, I guessed
$10.95 would not break me. I've paid for that, and it should be coming
to the UK by air.
I'm not sure what the copyright is on the material on that CD, but
anything I can legally distribute, I will for free. I don't want to make
lots of copies of it, but if anyone has a large anonymous ftp site, I
will either upload it, or perhaps send them the CD for them to upload. I
don't have the fast internet access with lots of disk space that I used
to have. If the data is only 20 Mb or so, I'll put on an ftp site here,
but otherwise I will have to seek help from someone with better
computing facilities than me.
I've also got some potentially interesting (and old) material taken
mainly from professional publications, but to be honest, the thought of
scanning it in on my £150 consumer-electronics SCSI scanner is not one I
relish. I expect it is the same with others. I find that scanning a 10
page data sheet, retouching in the Gimp (unix tool like Photoshop, but
better), converting to PDF with Ghostscript, takes the best part of an
hour.
I've put a few tube data sheets on the web
http://www.david-kirkby.co.uk/ham/data/index.html
but again I do have others, but are not willing to scan them unless
there is a specific need - it is just too time consuming. If anyone
wants one that I have, I'll add it.
PS, I added the full 4CX10000J data sheet a few days ago, as someone
wanted that. The quick, one page summery of the 4CX10000J on Eimac's web
site has a lot of errors, as the data is for another tube (Unless it has
been removed or corrected, as Eimac are aware of it).
