It would be interesting to know the efficiency of the Expert amp at
various voltage/power levels.

I just did a quick check:
At 1500 watts eff is 56% and pwr diss is 1179 watts
1000 44 1273
500 30 1120
My Expert 1.3K-FA had 3 voltage levels:
48 volts for full power (1300 watts)
38 800 watts
32 450
I no longer have the amp so I can't check the eff at those
voltages and power levels.
73, Roger
