I didn't look at the tube chart before I put it away, but I assume you're correct. That does seem like an unusual use for it. I see the class A1 power output for that tube is about 3 watts.
I'm a little ticked at samswebsite right now. I purchased two e-files that were supposed to be for the Zenith G3276Z and one turned out to be for a Sparton radio and the other for a Teletone television. I had hoped to check out the 6AG7 circuit, among other things.
