Hi all,
         I just repaired linear power supply for a fellow ham here and seeng
as it has an Ammeter on the front panel I decided to see if I had any one
band more "power" efficient than any other.
Here is what I got on the sampled bands.( using the K2/100)
80m   110w   15 amps
40m   110w   14 amps
20m   110w   14 amps
15m   110w   17 amps
10m    99w    15 amps
Voltage on the power supply was 13.55v
Possibly not the most scientific test that has been done on the K2, but
interesting enough. I was using the external antennas, and tuning each
carefully for 1:1 SWR before whacking in full power.
The power readings were taken off the K2 and looked pretty close on my
external ATU's Fwd power meter.
