Expat Audio’s “Uber Power Supply” PCB provides an adjustable bipolar voltage as well as 48VDC phantom power from a single or dual-secondary transformer. The desired output voltages can be set during the build with different resistor values.

Uber Power Supply Features:

• Based on the CRC power supply design, modified for more flexibility
• Uses Cockroft-Walton voltage multiplier circuit for low-noise phantom power

Price:

• $12.95 for PCB
• adjusted cost: $24.82
