Can’t buy output tubes anywhere except from manufacturers at high prices.

Sounds like a monster opportunity for the new Western Electric factory. Hope they can step up and put U.S.A. tubes back on the map.

Note to self:

Don't buy tube amps, someone else will enjoy more.

Hi,
A good friend of mine has a huge collection of tubes. He is now quite old and wants to sell off his tubes. He has advanced mesuring equipment as well so that he can check the tubes before shipping.

Please list the tubes that you need and I will forward your request to him.

Kind regards
Jaan

A young kid in this part of the world started a tube sourcing venture recently...he seems to have a lot of inventory.  I have zero frame of reference as I'm all SS.  Has anyone used them?

Adding insult to injury, current production KT150 tubes have reliability issues. I have an amp that uses four KT150s. In less than 200 hours, I lost three tubes; one for loss of vacuum and two others big flash, pop.
