Nope. I actively ignore stuff like this. Why not stick with 6SN7s (modern production or vintage NOS) actually built to the specs of those venerable medium mu twin triodes?

Quick history of the 6SN7 (which dates back to the end of the 1930s, just before WWII) here:

CV181 is a 6SN7

Yes, I know. My point stands. Why buy weirdly fashioned current production tubes, when the (edit) technology, expertise, fabrication equipment, and materials that went in to the vacuum tubes produced in the 1950s and 1960s were all at their zenith(s)? Especially when the weird, "designer" tubes are outrageously expensive?

I don’t have any experience with those, but at ~$100/each I think you’re closing in on NOS prices (although it’s been years since I’ve bought any).

I’d lean toward RCA or Tung-Sol NOS for that $$. Bullet proof and will last for years and years.

Exactly so.
