The Muffsy Hifi Dual Power Supply Kit is available at $39 + shipping.
The Muffsy Hifi Dual Power Supply uses a 15-18 VAC wall adapter, so you don't have to handle mains power.
Please note that the AC wall adapter is not included in the kit. See this page for options.
This +/-15V regulated dual power supply has only 0.1 mV ripple. The PSU provides up to 200 mA of power, with heat sinks mounted. It will power four of the Muffsy PP-4 without the heat sinks.
It is designed for hifi equipment, such as the Muffsy Phono Preamp or other high quality preamps.
There is also a second regulated DC power supply on-board, capable of delivering 0.5A of 15V DC. It even has space for a current limiting LED resistor.

This kit is meant to be paired with a preamplifier circuit, such as the Muffsy BSTRD Class-A Tube Preamp, Pass Labs B1 and many others.
This great Class A Tube Preamp is sold as two PCBS, the preamp itself and a power supply. Visit the hackaday.io project page for a wealth of information.
Due to the fact that this preamp is sold as PCBs only, there is no support offered on this product. Everything needed to build the preamp is available on the hackaday.io project page, including shopping cart for the components.
