Source for Svetlana SV572-10 or SV811-10 Tubes?

[Imago]

Now that I have my old Woodside SET 30 Triode amplifier running well, I should likely get a spare pair or quad of extra output tubes, although I hear they are very rugged and last a very long time. I think the fellow from Spain that helped me with photos from his unit has been running the same output tubes for 25 years!

Any reasonably priced leads would be most welcome.

Viva Tubes apparantly still has some. Not cheap but about the same as current 300Bs.

Here's a source for SV811-10's if it's legit:

Hi, I don’t know that particular tube but I bought some nice 6as7 equivalents from Timofey. On Facebook he is at https://www.facebook.com/profile.php?id=100024007716299&mibextid=LQQJ4d
