[Amps] Ameritron AL-1500 inquiry

[Larry Benko]

Jeff, Jim, and a few others who emailed me,

Has no one heard of places like FindChips and Octopart?  Don't waste 
your time going to distributors one at a time when places like FindChips 
will do it for you.

Go to http://www.findchips.com/avail?part=RT31C012 which shows Newark 
has 274 of them.

73,
Larry, W0QE
