[Amps] Fw: Henry 3 KD Premier with 8877

[Buzz Miklos]

Does anyone have any first hand experience with this amplifier?  I’m particularly interested in the 10 meter performance (Eb, Ib, Pi, Po).  Maximum power output at .9A of Ib is only 1200 watts with efficiency at 43%.  The lower frequencies are more typical for an 8877, ie, 1500 watts out with efficiency around 64% and Ib at .75A.  Any theories to explain the low efficiency on 10?
