    The Multi Amp aka Dynalo Mk2

    thanks all, I ordered. I know I'll have to handle SMD sooner or later. In the mean time, I am searching on the web regarding how to mount the TPS7A3301 and TPS7A4001 directly on the board. Maybe I could finish it before the modules arrive? Sam

    The Multi Amp aka Dynalo Mk2

    Please help me with the TPS7A3301 modules, I could only find this https://www.ebay.com/itm/TPS7A3301-Ultralow-noise-LDO-regulator-3V-18V-1V-step-1A-LM337-79x-replace/253593923500 It appears that it could only provide -18v, not the -20. Am I missing something? After spending half a day staring at the pcb without any progress. I gave up on soldering the chips to the board by myself.

    Transformer phase / no phase marking

    I used a 9v battery and a multi-meter. connect the 9v battery to the primary temporarily and see the fluctuated secondary output voltage to be positive or negative. then you know which way to go. I have not tried the KG methods but it appears to be very convenient.
  9. combined ship will be great

    goldenreference low voltage power supply

    Does the goldenreference low voltage provide enough juice for Dynahi? Use two for the Dynahi? I plan to make the Dynahi for the use of HiFiman HE-6.

    goldenreference low voltage power supply

    I am trying to make a power supply for my Auralic Aries mini. . The original one is labelled "switching PS 16v 1A" Any idea if the goldenreference can be used for such high current?
