RE: Speaker hum from integrated tube amp (Miniwatt N3)

Thanks for the response. It is definitely not the source, as it occurs when the source is not connected. (Probably moot, but FWIW I use it with a slimserver and a usb-powered dac.)

Do new tubes sometimes hum at first, and then stop over time?

Your mention of the headphones gave me an idea, and I tried switching from the 8 Ohm taps to the 6 Ohm. Way less hum. Does this fact help diagnose the problem? Is it okay for me to keep using 6 Ohm taps on 8 Ohm speakers? How about the 4 Ohm taps?

How is the bass on your Hsus? (Been shopping for new speakers for a friend)
