KPA500 voltage tap question

[RobertG]

Hello, all...

I've just finished assembling my KPA500 and have a question about selecting the
correct tap wire to set the operating voltage.

My 220v line reads 231v no load, so I selected the yellow tap. The amp no load
voltage is 71.7v. The transmitting voltage is 58v DC which is marginally low. If I
select the red tap then I expect I'll be marginally high. If my choice is between
marginally low and marginally high, which is the better choice? Thanks for comments.

Sure is a nice piece of equipment... as usual from Elecraft.

Try the red tap. So long as the idle voltage is still under 85V, go with it.
