|Elliott Sound Products||Project 05 Rev-D - Preamp Power Supply|
This supply is a replacement for earlier versions, all of which are superseded. Of course when you buy the PCB you get all the component values. The supply can be operated from a single 15 or 16V AC plug-pack wall transformer, or a 15-0-15 V transformer for maximum flexibility. 12V (or other voltage) operation is possible, just by changing the values of the voltage setting resistors.
The noise performance is excellent, due to the use of adjustable regulators, additional filtering and the high capacitance used. It has sufficient power for any preamp, electronic crossover network or any other (preamp) project shown on The Audio Pages. It can also be used to make a variable bench supply (as shown in Project 44). This version includes a complete muting circuit as well as the 'Loss of AC' detector provided on some earlier boards.
