Hi, your SB-220 sounds different than mine.
Mine is wired for standard house current, 120 volts I think it is.
Mine covers 40 through 10.
It doesn't have stand by on it.
It's supposed to be stock, no mods at all.
I've gotten 1800 watts on tune on 40 m.
I think my tubes are a little weak, the best I got on 20 is 900, and 15 and 
10 m the best was 600.
While I'm throwing in my 2 cents worth, there's a question I been meaning to 
ask the list.
Can you use the SB-220 on AM without hurting the amp?
Thanks in advance for any answers, and 7 3 to all.
