Alexander, thanks for posting those links.
I have been using a 955 (acorn) driving a P-P 5902 triode connected to drive a Klipsch La Scala for a few years. However both driver and power tubes are battery biased, 1.2V and 6V respectively. I use the small Hammond 125C as outputs. I don't have a schematic to share but my B+ is 110V. Nice sounding amp and I've been meaning to play around a bit more with it--also try a pentoded 5902 as a driver. So by all means dive into your project.
Matt
