SLA cells are indeed one way to go, but I didn't find they sounded better than a good current source filament supply when I tested a few different supply types. A supply consisting of two voltege regs followed by a common mode choke was pretty good. You'll need a heatsink with the 26 because the filaments are 1 amp, and the size will depend on the filament supply and the voltage dropped by the devices you use, but be prepared for something of a decent size.
