Has anyone had experience with this tube?

How can you get a great tone without a good understanding of what makes your amp tick? — EL34, EL84, 6L6, KT66, KT88, 12AX7, 12AT7, 12AU7, EF86, Output Transformers, Power Transformers, Capacitors, Resistors and everything else that it takes to make a tube amp sing!

Joe, I've heard this too about the power tube conversion, but note they have to be GOOD QUALITY 6L6GC tubes. I'm still skeptical about this, and hope somebody who's successfully done this posts about their experience.

the EH 7591 is really a 7591 and is your best bet short of NOS which is pricey. The earlier Sovtek version is the one that wasn't a real 7591, it was a 6l6 with a different pinout, and didn't work too well unless you modded the bias resistor. You can still convert to 6L6 or similar tubes if you want but I would try the EH tube first rather than mod a vintage amp.

I second everything that teleh said. If you decide to switch to 6L6 tubes (personally I wouldn't), 7581A tubes are a good choice. I'm planning on using the EH 7591A tubes as soon as I get a chance to service my '64 Reverberocket.
