Popular Post RickyV Posted May 24, 2020 Popular Post Share Posted May 24, 2020 Very nice build with excellent components. Do you have a schematic drawing of the components layout? And what does the SJ current booster do? This might be of interest too, https://evotronix.eu/main/ I bought 4 LC modules for the two nuc power supplies I am building.

I did put together a schematic and ran simulations for the pre-filter section before deciding what I will incorporate in this build, but since it may or may not fit other supply requirements, I will think about whether to post it here later. SJ current booster is a module Sean provide to help raise the output current from the base level at 1.5A to 5A. This supply will have two, wired in parallel to raise the output current up to 10A. The output Sean provide is quite conservative, actual maximum output can be higher, but other considerations will need to be planned more carefully, such as heat dissipation, transformer rating...etc. Ah you have the SJ regulators too, that why I was confused about the booster modul. Does SJ sell the regulators now to anyone? And may I ask what they cost? Meitner ma1 v2 dac, Sovereign preamp and power amp, DIY speakers, scan speak illuminator.

The only component on the front panel is the 25W power resistor between the two pre-filter capacitors. It will also have the high current Neotech 12 AWG solid core copper wire soldered to both terminals. Two bypass capacitors were also added to the second pre-filter capacitor, a 4.7uF Mundorf Aluminum Oil Series Metalized Oil-Impregnated Polypropylene film capacitor and a KEMET 0.1uF C0G (NP0) ceramic capacitor to help blocking the high frequency noise. Here is an overview of the progress thus far: Next up is the transformer installation...heavy stuff! Wow cool Elan really nice clean build. Also thanks for sharing the bypass capacitor values. What I couldn't see clearly was if you use one or two output connectors, looks like one 4 pole. Meitner ma1 v2 dac, Sovereign preamp and power amp, DIY speakers, scan speak illuminator.
