Will take pic when I get home. They’re connected with three powers/safety ground, BUT many of the receptacles in my home do not have safety ground wired. In fact, I’ve yet to find one that does.
I’m using two of these: GST40A24-P1J MEAN WELL USA Inc. | Power Supplies - External/Internal (Off-Board) | DigiKey
check with ohmmeter - is center pin of IEC (safety GND ) connected with negative leg , on output side ?
No, doesn’t appear to be continuity there. I’ve attached a pic of the ‘PSU’ in one frame. I originally had planned to connect each SMPS via separate barrel connectors, but my jacks are in contact with chassis. For right now I’ve just wired SMPS’s directly to the cap bank. The barrel jack in the photo is not connected.

Question on input impedance of the BA-3 - Nelson's article states that the 47K resistor to ground on the input sets the nominal input impedance. Is this the actual impedance? I want to calculate the value of the output coupling cap on a source.
Well you see them in signature except I did build Aleph J
In my F6 box. Will revisit it later with Semisouth outputs.
It just didn't get me like the others and I felt F5 did it similarly.

hello does anyone in europe have a BA-3 pre-amp card that they can sell me? or some components? i have a pair of original j74 / k170 and wanted to put it to good use. thanks
Thanks again to ZM and 6L6 for your help on this. Still need to finalize wiring and reroute, but it’s up and running. Sounds great!
Hope to build a proper PSU soon, but the two SMPS bricks are working great for now.
