I did push-pull-parallel ULTRALINEAR with similar tubes. In ultralinear, all you have to remember to get it to work right is do NOT neglect the screen resistor, use about 1K or 1200 ohms on each screen. This forces the tubes to power share appropriately and you will not need anode resistors. if you are doing it ultralinear, I can help you out. I have never built one any other way.

I only use Edcor and I would use 5K. for audiophile, it is okay to go a bit higher in impedance, it makes for better sound. for guitar amps, the opposite holds true. I made a 6V6 amp with the Conn organ schematic and hammond ultralinear 10K 10 watt transformers and it sounds good. I modded the schematic to use 6SN7 and can supply you all the proper values. it is a very simple build and works very well.
