Hi,
Exactly.
Sometimes you can still find some with a CV number but you really need to dig deep and hard to finf them.........
We'll never know.....They never made any.
Another little nugget is the Brimar 13D3 but it's a medium mu type.
Cheers, 😉

Do you (or anyone else) have any measurements on the a2900? I'd be interested in spectral distribution, especially fifth relative to third.
Hi,
Unfortunately I don't have it on paper anymore but we did run comparative tests of various popular tubes that struck us as particularly good sounding.
It may not come as a surprise but the test results coincided very well with what people reported as good sounding tubes and it's exactly those types and brands that are still being sought after by many tube-o-philes all over the globe.
Typical small signal tubes were EF86, ECC81-2-3, ECC88 and equivalents.
Popular power tubes were the KT88, KT66, EL34, EL84 and American 6550, A and 6CA7, 6BQ5, 7320, 7189.
From the American tubes the 7xxx series were particularly good for audio use.
The US power tubes often had far more grunt in the bass department at the expense of refinement subjectively speaking.
The list goes on and on but suffice it say that in general people distinguished between tubes quite accurately.
I assume the same holds true among audiophiles the other side of the pond.
You mean percentage-wise?
Ciao, 😉
