Hi all!

I have been holding on to a pair of rare vaccum tubes for quite some time now... but I never got the time or money to put them into use.

I've stumbled upon a website selling same brand and models for high prices and if I get to use them I'll never be able to replace one/both then they wear out.

part from ebay, does anyone know were to list these toys ?
I have tested them both and they have about the same characteristics (even tho they are marked as 311T and 311CT) they were branded/used as a pair when I got them in a old vintage equipment, retired obviously due to age and not being practical.

if anyone is interested on those, please let me know and we can sort out a test setup if needed.

I need to turn money around to cover expenses on electrical and roof work on my house. later on I might be able to get a 300B amp or some KT88 in memory of this ones that I can't really put to use
