Thank you for your comments. To my prejudiced ears, it sounds very good. I'm running it through Paradigm Studio 20s and it drives them effortlessly. I think triodes have a chrystalline quality and pentodes have a solidity to them. This is definitely a pentode amp, but there's a bit of that triode shimmer in its sound. Music is engaging and lively.
Here's the schematic. The B+ is being rectified by a 5U4 instead of a 5AR4 so the actual voltage is closer to 300 than 335.
