E180F tube

[kuly]

I put together a circuit - it works the first lamp e180f (my tube is telefunken) who has experience!?
What company that produced such lamps has the smallest microphone effect; my lamp makes noise at the slightest touch — which company is good?

1-Tesla
2-Telefunken(big microphone effect)
3-Valvo
looking for a good tube

Well, the E180F isn't exactly known for low microphony 🙄.


Best regards!

What company has released the last batch? what year? These lamps should be good
I think Mullard

Try 6Ж9П-Е and 6Ж49П-Д

Also, 6С3П and 6С4П

.......I knock on the lamp on the body there is not the slightest sound --- great lamp !!!!
