[Amps] output of SB220 typical TSPA

[Will Matney]

John,

I don't think line voltage would amount to much, maybe 50-60 VDC more if there was a 5 VAC raise on the 
line. I don't think that's enough to get 200 more watts. My guess is the wattmeters some use are a little loose.
I've seen this many times where they were off this much.

Best,

Will
