with regards to the t2 voltage issue, I was doing some more research and came across these (partial) posts:

"George thank you very much. I really don't know which Boss i have. Is there a way to find that out?
The output voltage (T2) wire 15-16 was 74VAC. I don't know why but somebody put wire 15 on the wrong output. Strange that it ever worked. So I put it back on the original place and its 64.4VAC...."

and

"Moving these motors is a matter of energy. Volts X amps equals watts. I fnow the 230 V transformer uses taps 5 and 6. What do yo have in volts AC between taps 5 and 7? If it is 63 volts or less then I would move the wires from taps 6 to taps 7."

So I tested taps 5-7 and they give 10 volts higher, approx 84 vs approx 74. I was working from and extremely poor copy of the schematic for the voltage changeover, coud you confirm that the following is the correct wiring for the primary side of t2?:

L1 to leftmost terminal 1 then jumpered to leftmost terminal 3 and center terminal 4
L2 to center terminal 1 then jumpered to center terminal 3 and rightmost terminal 4
L3 to rightmost terminal 1 then jumpered to rightmost terminal 3 and leftmost terminal 4.

I suspect the last jumpers may be out of order and should be center/center/center, middle/middle/middle, right/right/right but don't know if this would (a) cause the voltage issue or (b) cause a problem (smoke!) if I "corrected" it.

seems I know just enough to screw things up sometimes, gotta learn somehow though! outputs are 16/14/12 to the #5 taps and 15/13/11 to the 6 taps, in that order from left to right.

thanks
