[Elecraft] Considering KPA500/KAT500 Combo with Flex 6500

[Don Wilhelm]

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.

73,
