Re: [amsat-bb] Re: Drake 2880 power

[Bill Richarz <wricharz@xxxxxxxx>]

I went to RS and found two inline preamp power supplies
that might work.  One is rated at 18V @ 50 ma.
The other is rated at 12V @ 200 ma..

Was wondering, will either one of these or both work?
The 18V one is $30 and the 12V is $25.  I forgot what
the original PS was rated at.
