It arrived last night. A quick look at the board confirmed the tube is in the circuit, but it is a cathode follower, no gain.
OK, not a big deal, do more research next time. The power supply must be 12VAC since the four transistors are used in a 30V+/- split supply and there is a 7805 voltage regulator for the tube heater.
I'll see how it sounds this weekend. In the meantime it does give me an idea to play with to maybe convert it to a gain stage.
Still easily worth the $22.80 I spent.
more to follow...
