Thanks, actually there was more there than you thought you were giving and gives me a better idea of the pros' and cons of the 1/2 triode usage (in context). That's the meat of matter

I've never used that tube, but supposedly it is a good tube for that purpose. However, I'd just use the transformer as output device directly. Assuming (oops, I am diverting the subject too) you have a current out DAC into a low ohmage resistor then into the transformer, you'll have a good low impedance drive for the cable and preamp. The only reason to build a tube stage after the tranny is more gain. I use my CDP with only a 50ohm resistor as the I/V converter into a Lundahl 1:1 transformer. The signal level is about the same as my phone pre, so relative to my DVD player, I turn the volume down a tad when watching movies. Oops...sorry, didn't answer your question.
The pros of using a single triode vs many in parallel is simplisity. The single triode section can probably run hotter than when using both b/c of heat from the neighboring triode isn't an issue. This may potentially be good? Cons is higher impedance, but is it high enough to matter, think not. Sorry man, I'm not helping. At least I can give my vote to running transformer direct, no gain stage at all.
