A few pages about tubes

From Jindra OK1XR, we got tips on some interesting tube sites. I considered, or compile some kind of compilation from the materials on these pages, I finally said to myself, that it wouldn't be that, and that's why I'd rather bring you the email in “original text without subtitles”. TNX Store!

Hi Oliver. I am sending several types to interesting pages on the topic of power tubes for PA .
http://el-tubes.webzone.ru/reference.htm – pages with the parameters of some Russian broadcasting tubes in .zip format .
http://ru3ga.qrz.ru/pa.shtml – RU3GA technical site, e.g. Linear amplifier with modified GU81M
http://www.tubecollector.org/ – the Virtual Valve Museum site – pictures of tubes
http://www.eugen-elektronik.de/ – specifications and parameters of end tubes including prices in Euro
http://hamradio.online.ru – Technically, a portal of Russian radio amateurs with a wide range of topics.
I would say, that it is more interesting than cut duralumin tubes in a bag.
