  Wanted  

In the unlikely event that you want to get rid of electron tube data books: please don't throw them away, but send them to me.... Many people can benefit from them if added to my tube data book collection.
It would be great to have some more mirror-sites for the tube-datasheets! If anyone, anywhere has a server and bandwidth, and a little spare time to manage things (probably also loves electron tubes) you could host another mirror. I am not able to pay for any costs (I don't earn anything with the tubedata website). Maybe someone at a University for instance can have 'free' access to the net. As we already have a mirror site in Poland and two in Germany, it would be nice if there were some more mirror-sites in other parts of the world. The amount of data is currently about 7.5 GBytes and data-traffic is about 1GB per mirror each day! So having more mirror-sites will probably reduce the amount of traffic per server and provide better accessibility to the tube-data for everyone. We use RSYNC for mirroring.

Tube data requests:
An original datasheet with curves for the 45Special=VT52=2C45=38142 output triode would be great. (This is not the VT52=EL32 output pentode.) It seems data for this tube is rare and desirable.
