Back from LSAF2023 and now for some more fun with Pizza Box Amp v2.1.

These are the fanless SMPS for +/-36V at 1kW DC output.  Should do well up to 500W without a heatsink or chassis mounting for trials.

They have adjustable output voltage, so will be making sure both sides are as equal as possible.

Next to wire them up for testing with a resistor load check.

They look like MeanWell SMPS.  Are they?
