...so it looks like it has two power tubes, but really has only one...or...they are using the pentode sides for output power and the triode sides for preamp and PI? Do I understand that right?

Is this tube sort a like a 12DW7, that has two disimilar sections?

Correct, Bill! The 6BM8 has, effectively, 1/2 of a 12ax7 as well as a pentode to provide the shove through the speaker.
Two pentodes, two gain stages, one phase inverter, one trem oscillator.

I'd say "I love it when you talk dirty" but that would be TMI.

Univox U60A. Same exact amp, but Univox branded. On Evilbay

The seller is LTGer Noah Miller and these are his Valco Pages.

Everything Noah says about it is true. It's a nice low-wattage mudbox - perfect for a saturdaynight jam along with the radio!
