Steve,
about Gamma HPS-1
What kind of experience and how long you have used it.
You told it is NOISY.
Did you ground your equipments properly?
The many evaluations of the supply seem to be
strictly positive (5/5). Of course they have bought
it and want to say they make wisew decisions.
I have not found this noisy. Quality varies ???
I made the modification 2k to 2k7 resistor change,
and aural noise will be blocked. Fan is silent (still).
