Sigma 22 Power Supply kit

The Sigma 22 is a discrete, dual rail, fully complementary tracking regulated power supply. Included are heat sinks, Nichicon UPW and UHE Caps, Wima film caps, Vishay/Dale resistors, and the PC board from AMB labs. We offer three output levels 50 VA (-8.24), 80 VA or 100 VA (+ 6.69), or no transformer; based on the planned use for the power supply. Just add an enclosure and hookup wire and solder and you will be ready to build. The kit with the 80 VA transformer is recommended for powering a three board Beta 22 headphone amplifier.
