Power Supply for Preamplifiers

Posted on Feb 11, 2013

Preamps may in some cases use a simple regulator, with the supplies taken from the main amp power supply. This can be a problem if the main amp is of very high power, as the supply voltage will be too high for 3-terminal regulator ICs. This will also be a problem if the main amp is under warranty or you just don`t want to fiddle with it.
