In Reply to: RE: SET headphone amp without hum? posted by aarocks on August 06, 2016 at 05:25:20
WA6 SET headphone amp is dead quiet. If it does have any hum it's tube, connector, or ground related.
When I first turned my WA6 on at full volume there was a very small hum. When I changed out the rectifier tube and the drivers tubes for 6SN7's and the Sophia Mesh Plate 247 tube it was dead quiet at full volume.
At normal listening levels there was no noticeable hum with any of the tubes.
Hope this helps!

So if I have ground loop issues I will get hum from the WA6? I don't know if I do but I might and I rent. Do any SET headphone amps not produce hum even if there is a ground loop?
A ground loop of the type you're referring to would mean an external fault is injecting hum into the amplifier. No amplifier can protect you from that.
Buy Chinese. Bury freedom.
