New 6CA7 EH powertubes

Has anyone tried the new 6CA7 EH powertubes lately? I'm curious to see if they sound like the old GE/Sylvania tubes.

I tried them in my '72 50w. Sounds nice, extra low-end, more full range. I had to add 22k in series with the bias pot to get them to bias correctly. Nice for a 50w to add some bass.
