Hi All, a friend of mine built an amp using the 6B4G and said it hums fairly loud. How much hum is there in the GSG amp? I see in the schematic there is a very extensive filiment PS cuircut.

Mine is quiet as a stone. I've got some 100+ dB efficient Klipsch Chorus II, so any hum would be noticed and offensive. The Get*Set*Go does not hum.

Great to know Ty as I am using it as the front end of my GM70 amp and that tube will then amplify any hum going into it.
