I looked at the 2 pin thing, and it's wired into the heaters of all the tubes with some really thick wire. I suppose it's possible that the heater circuit is the 2-pin, and the rest is B+ type stuff on the 7-pin one.
So you don't actually have the power supply for this set? Did it go missing? And won't that slow down getting it going?
