Greetings, I was looking my SB-200 over and noted the model plate reads SB-201, serial number 01922. Was the 201 an update? Any way to know when it was manufactured? 73 de Tom, K4NR -- FAQ on WWW: http://www.contesting.com/ampfaq.html Submissions: amps@contesting.com Administrative requests: amps-REQUEST@contesting.com Problems: owner-amps@contesting.com Search: http://www.contesting.com/km9p/search.htm
