I got a new K line from Santa (N1GMR) and built the K3 (loaded) and P3 in 1 day. Works perfectly.
The KPA500 I had to assemble the next day. ;-) The amp came from W6 with a 120 V line cord, so, I used that and plugged into one of the three 20A 120 V circuits I have here in the shack. Independent breaker. 12 AWG. The PA made full power easily, ~76 V on the drains. However, I did notice a bit of ceiling light flicker. The color-temp-controlled halogens are on a Lutron dimmer and *any* voltage delta will show up on these bulbs. So, I went to Stay On Line and bought their part #4833, a hospital-grade NEMA 6-15 to IEC60320 cable, 3' long. Cost was $9. This plugs into my 240 V outlet. Now, the same amp at the same drive level puts out a smidgen more peak power (~30W on the calibrated LP-100; unloaded HV 76.5 V, ~63 V loaded). And, what is better, no ceiling light flicker, even with my very sensitive ambient lighting. If you do the same thing, don't forget to flip the line voltage selector and change the fuses!! This story is brought to you by Georg Ohm and Leon Thevenin. I stand on the shoulders of giants. Happy New Year to all. I will try to be on for SKN. 2011 Elecraft K3 keyed by a 1942 Lionel J-38 operated by a 1961 Jackson Wise Acre, Serial #1. Life's good.
