I just ordered the Samlex 1235P-M, which is a newer version of the 1235-M,
I've never detected any RFI from my 1235M, and it has worked flawlessly
for about 15 years. It may be an old design, but I really think they got
it right. It's quiet, reliable, small, and inexpensive. What more do we
want? It's not like the latest generation of 2 nm (or whatever)
semiconductor technology is going to improve a simple power supply.
That said, there are a lot of other switching supplies out there which
are NOT RFI quiet.
