Can you identify this DIY tube amp PCB?

I've got this unknown amp new PCB, it indicates 6BM8 tubes in the small text. Text reads: Experimenter's 6BM8 Push Pull Stereo Amplifier...Richard Sears Rev 051810. Does anybody know this board or have a schematic for it? Seems a waste to throw it away.

I messaged him at triodeguy.com, the email doesn't bounce back, so I think it's an active site, no reply yet. Browser gets refused by some protection the site uses, so can't browse there. Found his old site using wayback machine, there's nothing there about the board I can find.
