I'd like to have a non-magnetic parts list here on the forum, as this seems to be a 'item of concern' for the more aware of us, when it comes to sonic quality-at it's finest. I ended up thinking about making such a thread that was and is -specific-, due to having little in the way of a specific thread on the forum! After an hour of searching, I decided that frustration would be the norm, and to attempt to remove that aspect for the next guy who does the same search. I mention dates on some parts,as things might change on the more expensive stuff which is low volume and is built specifically for it's sonic qualities. For example, on the later mentioned Teflon tube sockets that are $25 each - they might get wise and make a change. You see, the parts are supposed to be OFC and 24k gold plated--and that's it. But testing is showing that a bit of magnetic material is in there.....
Whatever the item series of devices, if you know it is non-magnetic, be it resistor, capacitor, transistor (yes-possible!) or whatever (sockets, switches, and potentiometers), please add to the list.
Please report in the given item it if IS magnetic as well, to help remove doubt, or doubt would abound-if the given specific item was not mentioned here. Also, some parts like resistors can be 'slightly less' magnetic than others, so might serve well, when it comes to being a second choice.
I was specifically searching for non-magnetic electrolytic capacitors.
So far, I've come across..in my pile'o'stuff......:
Rubycon 'Black Gate' electrolytics: Non-Magnetic
Elna Cera-Fine Electrolytics: Non-Magnetic
Elna SilMic Electrolytics: Non-Magnetic
Sanyo Os-Con Capacitors: Non-Magnetic (purple skinned)
Sprague 'Os-Con' capacitors: MAGNETIC! (Older series-blue skinned)
Most (near 100%-I mean, tell me if there is one series that isn't!) of all Panasonic Electrolytics: MAGNETIC
Most all series of Nichicon Electrolytics: MAGNETIC
Most all series of United Chemicon Electrolytics: MAGNETIC
'LittleFuse' ceramic bodied pigtail fuses: Non-magnetic
'Connex' teflon sockets at 'the parts connexion': the mini-9 pin sockets components (the metal bits) are VERY mildly magnetic. (tested 7/20/2008, a 7/26/2006 purchase)
Vampire Wire OFC Female inside mount RCA jacks: Mildly magnetic
Xhadow OFC speaker spades: Mildly Magnetic
