Kevin,
I would suggest that you get an electrician to check the wiring to that
outlet and the end in the breaker box. That sounds like too much AC
line drop to me.
You may have to do that check on all outlets on that AC circuit. If
they are wired with "Backstab" connections, those connections should be
changed to move the wires under the screwheads.
Failure to do so can result in overheating a poor AC junction, and in
the worst case a fire.
I would attend to that matter before changing the transformer tap.
If you are calling in an electrician, you might be better off to have
him run a dedicated 240 volt line to the shack, but while that would
solve the problem for the KPA500, my feeling is that you still would
have a potentially hazardous situation in the AC circuit you are
currently using.

Hi Bill.
A Fluke plugged into the same outlet shows 120.0 VAC unkeyed and 116.9 VAC
(60 V internal) keyed with 190 watts out. 114.4 (55 V internal) with 500
watts out.
