Rerurn to Romy the Cat's Site

If you don't already know of it, here is a link to interesting German site (in English as well) with loads of info on Tube testers :

http://www.jacmusic.com/Tube-testers/index.html

If you scroll down to this phrase :
"SHORT OVERVIEW OF TUBE TESTER FEATURES IN EXEL FORMAT", there is a link to an Excel chart listing features of several testers.

I will try linking it via html :
http://209.85.135.104/search?q=cache:-wZJjydu-NkJ:www.jacmusic.com/Tube-testers/overview.xls

... If I read correctly, a few of the testers appear to use DC plate current (?).
