You probably came to this web page because you have an Astron supply that has problems. Note that the Astron supplies are advertised with peak duty amperage numbers and in continuous duty can supply only about half of the rated current that is, a twenty amp Astron can in reality supply only about ten amps continuously. Astron marketing gets around that by saying that in normal operation the user listens i. This gives time for the heat sink and pass transistors to cool down. In other words, the digits in the model number represent the peak intermittent current capacity.

Astron RS35A 35 Amp Power Supply
This thing is big and heavy. Most ham radio transceivers do not run directly off of mains AC power, but instead operate from about Keeping the power supply in a separate unit from the radio makes the radio lighter and cheaper, and allows the heat from the power supply to stay far away from the radio. It also allows a radio to operate easily off of 12V lead-acid batteries, or automotive electrical systems.
A look at the Astron RS-35A
Note: there is an Astron Wireless Technologies company that makes some very nice antennas. It is a totally separate operation with no connections to the Astron Corporation that makes power supplies. Astron makes both linear and switching power supplies, and some other products.
