Is this the end of the tube amp?

[scottosan]

Panic buying. Most people change their tubes way too often. Then there’s a literal metric shit-ton of useable used tubes that test as new because of my prior comment on people programmed to think they need to change their tubes yearly.

I believe TAD is a reseller of tubes within certain "higher quality" specs. Dont believe they Manufacture/make tubes.

Germany is still buying Russian oil, so O don’t see why they’d sanction tubes

I have had the exact same tubes in my LARRY DINO now for over 3 1/2 years,
Every once in a while, I take them out and test them…
They haven’t even changed one percent, None of them…it’s weird,
I have other amplifiers that eat tubes, like the Bogner 100B’s.
Larry must have everything running at perfect optimum levels for tone and longevity.
I crank it many hours a week, so it’s not as if a baby it…I really don’t understand it.
But it’s all good

The key word is "parasitic oscillation"
You can't hear it, even not your dog - and the speakers anyway don't transfer such high frequencies.
But they are there.
In 4 of 5 of all old Marshall amps, in Hiwatt's, Orange's, aso.
And they strain the power tubes additionally sometimes not insignificant.
The reason is a sometimes terrifying disadvantageous lead dress.
They haven't spent enough attention to the lead dress, disregarding the fact, that each lead is a sender and a receiver of sometimes huge stray fields.
Later amp builder, especially those who are using Marshall style amp chassis for their builds often simply have adapted it.
Maybe by thinking: "If Marshall has wired it this way, it must be right"?
But no! Many later amp builder obviously simply have copied & pasted the mistakes of the famous antetypes?
Those amp builders, who have read all my 4,650 posts at forum.metropoulos.net/ should know, how to do it 'right'
Good night! (02:10 am here in Germany)

We'll probably be using more Chinese tubes in the future, and complain about how they don't sound as good, even though the difference will barely be audible.

Craig is the man. Just ordered 40 12ax7’s from him. And 7 quads of power tubes with 15 more quads pending.

Granted, I’m not panic buying for myself. I have builds to build.

Man you wiped him out !!
