What power supply should I use with the IC-746?

Short Answer
Any good quality, communications grade, power supply rated at least 20 amps or more
(continuous duty) should do just fine. However, most of us use larger supplies (for a variety
of reasons).

Long Answer
This question typically arises for one of two reasons. Either someone wants to buy a new
power supply, or they have an existing power supply that they want to use. In both cases, the
issues are: load capacity, size, weight, electrical noise, mechanical noise, cost, features, and
appearance. Buying a new supply gives you a lot of options; there are plenty of great
supplies out there. With an existing supply, you have no control over these factors; you're
simply looking for a "fit".
You'll want to consider the following factors.
