TypeSingle Unit (±5/8/12/15V & 3.3/5/6.5V) - $69

Your projects need a low voltage power supply. Very low noise. No hum, no mains pops. Efficient and portable.

Enter the SilentSwitcher by Linear Audio:

  • Very small (2.2x1.3in; 56x32mm)
  • New V3 version has pads for resistors to customize the output voltage, see the information at
  • Primary output: Your choice of ±15V, ±12V, ±8V or ±5V at 150ma. Jan has posted some notes detailing how ±18V (at 100ma) and ±24V (at 50ma) are also possible if you add your own resistors. 
  • Secondary output: Your choice of 6.5V or 5V or 3.3V at a minimum 0.5A
  • Efficient, cool running
  • Runs from a USB charger or from a powerbank for total mains separation

There's no longer an excuse for a noisy or humming preamp or DAC or active crossover! You can read more about the product here:

Perfect power module

Great power supply. It is very quiet, perfect for that op-amp based MM/MC pre-amp. The 5v easily powers the user interface processor, display and switching relays.

Fabien D.
excellent quality

I used it to power a 24v JFET preamp (had to do some slight modifications which are explained on the website to achieve the 24v but it was really easy) It's absolutely dead silent. I would Highly recommend it.

Outstanding performance, and a very convenient turn-key power supply. Jan does superb work.

Silent Switcher

Took a veeeeery long time to ship. Despite the board being made in Europe (and the UK was in the EU at that time), it was shipped from the USA which meant import taxes and VAT on top, plus a handling/service charge which effectively almost doubled the price of the board.

Although the board worked very well after it arrived, if was very expensive for a simple power supply.


SilentSwitcher works perfectly

SilentSwitcher works perfectly.
I use it to power DAC, battery and SilentSwitcher sound better than low noise linear power.
