[Amps] Amp Supply LK550

[Carl]

It works more efficient with 2 tubes if you are satisfied with 1500-1600W 
and that usually requires tweaking the input.
With 3 tubes it tends to be a bit unstable on 10M due to incomplete 
neutralization.

The usual padder and blocking cap caveats hold with all their amps except 
the LK-450 and LK-750.
