[Elecraft] Amp choices for QRP K3?

[Phil & Debbie Salas]

I just checked - my ALS-600 runs 80-100 watts out with 10 watts drive from 
my K3, though I normally run it at more like 500 watts output with about 70 
watts drive.  There is a 35 ohm resistor in series with the ALS-600 input 
that can probably be reduced to give you more output power.  I have modified 
my ALS-600 for QSK operation and it works great with my K3 (see this month's 
QST or www.ad5x.com for details).
