data sheet for EH 7591 power tube

Hello all, Does anyone here have the data sheet for the new Electro Harmonics EH 7591 power tube?  Thanks Punky

I've got one on a mis-placed USB stick for a JJ... not anywhere as comprehensive in data as the old sheets. (Now to find that stick.) I never found one for EH when I was looking for one.

Thanks Bill. I have a data sheet on the JJ. My main consern is the screen grid. On the NOS 7591 they say its best to connect both pins of the screen 4 & 8 together unless your running ultralinier @ 40% tap.

On that, I'd just wire it like on the old sheets, that way if you stick old tubes in, there will be no problems. These new ones are supposed to be pin for pin compatible anyway.  IF an EH sheet exists, I somehow don't picture it as being any more comprehensive than the JJ sheet.

Thanks Bill, I think your right on the new data sheets with squat for info. I will wire it to take old stock tubes to be safe.

New Sensor doesn't supply datasheets or any form of tech info on their tubes, their KT120 being the exception.
