[AMPS] SB-220: Operate/Standby Switch

Mauri,

I do recognize the overall gain does increase, but the efficiency does not.

I draw less mains power to get 500 watts of output on my SB220 on CW 
position than I do on the higher SSB position, when I decrease drive.

Look at the Rp current in CW mode.  It is almost half what it is when in SSB 
position...  Mo watts wasted as heat does not equal less watts drawn from 
the mains power.
