A 9V battery would be good there too.
(Rechargeable, of course)

Dan, absolutely, and it seems an obvious choice but I'm not a fan for several reasons. Mainly, as Jeff pointed out the maintenance which still may have been worth it for a sonic improvement but IMO it's not as good as a simple R in this instance.

I have no experience with parafeed preamps
but I would think the unbypassed cathode resistor
would increase the tube's output impedance
well beyond any transformers ability to
convey 20-20KHz response across it.

If this were a power amp I'd be more concerned however it's only a line stage not pushing much load. In addition, since a CCS is being used the essentially constant current through the Cathode R means very little degeneration.
Naz
battery on the cathode is also an option as the current there would help keep it charged, or at lease keep it long lived.
Tho I'm a bit concerned about the sonics... different animal I know but I was biasing my input tube on my 437a / 320BXLS with a 2.4vNiMh and change to Cree's, the difference was amazing. The Schottkies had a not insignificant difference to the sound quality for the better.

But comparing one 9V battery to 12 Crees might be a different story. We can both agree it's better than an electrolytic.
Although I have been curious of the (polyester film) cap linked below.

Web site says sold out :(
But lookey what I found on the good old e(vil)Bay....
Only 6 left... hmmm I wonder where the other two just went ;^)
