UF4007's.....are those quieter versions? I've never used them. I've got some 22 gauge teflon/silver wire. What gauge did you use?
UF4007s are quieter. I've never used any 1N parts for anything so I can't say if it's particularly noticeable to the ear, as opposed to test equipment. They're both ridiculously cheap so I just use the UFs. When I've used them in power supplies I've snubbed them with high voltage caps - 0.01uf 3000v. I wouldn't bother with snubbers in a bias supply like this. There are other types of diodes that are even quieter. I don't use diodes much so . . .
The wire I used was 20 gauge. The wire I replaced might have been thinner so 22 might work fine. It was more work but the original wire was pretty rough so I went with peace of mind - I wouldn't want faulty insulation to put 400+ volts onto the chassis. Ouch.
