Mine (I've got the console!) is on my bench - the horizontal section's giving me fits and it syncs like crap
hopefully i'll get it sorted out this fall.
The knob on the lever is the fine tuning adujstment, for when the cover's off. It's a weird set, that's for sure...
(And yes, a 25L6 with a step up auto XFMR for the vert output. Like I said, it's a weird set...)
