Anyone try the Groove Tube 6CA7 GE?

Thinking of trying these in Simul-Class Marks:

"The GT6CA7GE is the classic American-style EL34 tube made in the exact likeness of the famed General Electric 6CA7 tube of the 60's. This was the tube we sold to Eddie Van Halen for his Marshalls used on the first two Van Halen albums (often cited for his best tone on record).”

"The Groove Tubes 6CA7GE is a USA-style power pentode tube with similar specifications to the European style EL34 tube. However, the 6CA7 differs in design from the common EL34 types by the use of an active beam-forming electrode similar to that of the 6L6 and 6550. Groove Tubes purchased the actual GE production formulas, along with many of the original General Electric machines and vintage Plate materials via the closing of the GE tube factory several years ago. Using these original machines, the original components and their “secret processing recipe”, GT was able to authentically reproduce the classic GE power tube."

These are supposed to be a cross between a Eurpoean EL34 and a U.S. 6L6; a brighter, punchier version of the EL34. Before I abandon EL34s altogether, I thought I give them a shot. Anyone try them yet?

Let me know if you find anyone who has them "in stock".

they are a definite favorite in marks amongst those here who have been privileged enough to try them. I don't think they're in production right now though, hence Joey's response.

Don't know how close they are to the GE but I still have a pair of Mesa branded Sylvania 6CA7s from when I owned a Mark III Simul-Class MANY years ago. I have put them in a Music Man amp and they sounded stellar, also put one in my Frenzel Champ Plus for a few minutes and that was a purty ol' tone too. One of those times being a packrat has paid off!
