Actually, the SB-220 had the 10 meter band from the factory. It was the SB-221
that had to be "modified" to get the 10 meter band.
The same with the SB-200/SB-201. The SB-200 came with 10 meters and the SB-201
had to be modified.
The SB-200/SB-201 had a pair of 572B tubes; the SB-220/SB-221 had a pair of
3-500Z tubes; the SB-230 had a single 8873; and the SB-1000 had a single 3-500Z
tube.

Take it from me, ALL SB-220s had two 3-500s in them and only those. The SB-221
also had same, but had 10m.
The SB-200 had ONE 3-500.
