SB-221 120 vs 220

[Joe Cro N3IBX]

Tom,
       You should see between 600 and 800 out on 15 meters, and over 1200 out
on the other bands, even with 110 AC. What is your plate voltage? It should
be in the neighborhood of 2600 at about 350-400 ma.

Incidentally, the 3-500-C's are Chinese 3-500z's. They are good tubes
regardless of what some people may tell you.

Hope this helps.
