Today I discovered an advantage of using SMPS vs. linear supplies for experiments. The same applies to using current limited bench supplies.
It is more about having current limiting during experiments, rather than switching or linear, not ?
One can always incorporate current limiting in any linear supply, as we did in the F5X Preamp.

Even better, you can use a fold-back current limiter :

Only 3 transistors, gives you both voltage regulation and current limit that decreases with the amount of overload.

My experiences with SMPS power supplies are not so positive.
In my test bed I use two Mean Well LRS-150-24-AC-DC-6.5A-156W-24-V-DC modules connected in series with virtual ground to generate dual rail +/-24V.
It turned out that this configuration produces a disturbing component with around 110 Hz.
I would have understood 100 Hz, but 110 Hz must be the beat frequency.
Is there another explanation?
