(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 remember seeing a website some time ago offering conversions to silence PCs but didn't bookmark it.:( 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. Cheers Billy 8-{) |
