I would be quite happy having an external transfomer that had no sound.

147290 2003-05-25 04:30:00 I take it you mean "linear" power supplies, rather than the switch mode supplies which are univerally used . They are all "solid state" and 'electronic" . (I haven't seen valves in power supplies for a while --- except in transformers . I've got a VR98 on the wall --- 60 KV, 1A) .

I am sure you could get a linear supply, but there are two serious drawbacks: cost and weight . Have a feel of the weight of a 200-500 VA transfomer . Look at the price tag .

A third problem --- much lower efficiency --- might make the "sound" problem worse . . . linear supplies need more cooling .

Sorry, there has been some progress . :D

I installed an ancient Compaq PSU in Old Faithfull when the original supply failed. It has a huge fan with sculpted, aerodynamically shaped blades and is virtually silent. All I hear are the two HDDs.
