Thanks for all the responses to my inquiry - some very different opinions so
I'm still not sure of the correct answer.  Please be advised that the Alpha 
series amps do not have taps for different input voltages - only 115/220V.
If they did that would certainly be an obvious and easy solution to the 

Any further suggestions appreciated.

My ALPHA 87A manual shows taps on the primary to handle 200, 220 and 240vac
international requirements.
