Jed I use an SB221. I strongly suggest a "soft key" device for the amp.
Mine also has a soft start, Harbaugh filter caps, and a standby switch. Tune it with a pulser - see Inrad, etc. I run on 110v, that limits the output of the amp, but 30 watts into it shows 300 watts going out. Cheers, Don [Elecraft] [K3] Using K3 with Healthkit SB-220 Jed Petrovich jwpetrov at gmail.com Fri Dec 11 16:35:13 EST 2009 Hello all: I just recently purchased a SB-220 amp. I would appreciate any tips from other users that would help me with this setup. I'm most interested in what K3 settings (power, etc.) are used during tuning. This is likely NOT a general interest topic, so PLEASE feel free to contact me directly. 73, Jed AD7KG K3 #2826 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
