The PA-12 was going to have to sink or swim while driving the Basszilla Platinum Edition mk2 DIY speakers. The Basszilla, being a 96 dB sensitive loudspeaker, is quite comfortable with low-power tube amplification. And field feedback had it the coupling of the Basszilla with a Futterman style OTL sounds superb, so I expected this to be a successful marriage. As you will shortly see, I was not disappointed...
