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.
Beware of eBay..... people find an ad, copy most of its meaning, not the
exact words, and offer it. If people are fool enuf to send in money, the
product and the lister disappear. First test is a phone call and the
seller is not a ham, etc. 73
