Hello,
I’m new in this group and I want to share my lab analog power supply especial designed for high end preamps.
with +/- 22 Volt supply voltage ( I like this ! )
The performance is pretty good, low noise low ripple and hum are the key aspects. You find a measurement (Conditions: 2x12 V, Iload: 2x250 mA ; Analyzer: Audio Precision One) of the noise spectrum compare with battery and commercial stuff in the attachment.
Conditions: 2x12V, 2x250mA
Specification:
Output Voltage: 2x12 Volt - 2x26 Volt, adjustable
Current: 2x250 mA ( depends on In-/Out Voltage )
Protection: reverse voltage ,reverse biasing, mutual shutdown
Comments are welcome...
