Thank you for the link.  Looks like they have good product offerings.

 

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?

Once the back panel output section wiring is done, it's time to move to the front panel.  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.

Never mind the question about the output connector, confused again.
