Hum from Tube Amplifier

Forums

Hi all,
I'm trying out a Vellman (Dynaco) Stereo 70 tube amp, with integrated volume control from a local shop and I have a hum from my speakers which does attinuate when you raise the volume control with ot without a source connected.
I have the (I believe Integrated Amp since I have to use my pre-amps tapeout loop for connection to the amp) powered through a power line conditioner (tried without too) and sitting in my rack under the other equipment (3rd shelf down).

I have tried to connect a seperate ground from chassis to ground and no change.

Good live LP recommendations

The quality of live albums usually range from bad to terrible, but there are some of them that can be just great. I was listening to the Bob Dylan 300th, or maybe it was 30th anniversary set. I was set back on my heels (no mean feat when you consider I was sitting at the time) by how good some of it was. "You Ain't Goin' Nowhere" sung by Shawn Colvin, Mary Chapin Carpenter, and Roseanne Cash was just wonderful. Stevie Wonder on the other hand is awful, but there is A LOT of great music that even sounds good.

What are your favorites, and why?

End of Jazz Radio in Chicago

Forums

WBEZ the last surviving all jazz FM station operating in Chicago recently announced that within a year they will change format - to talk radio. Obviously the world needs more talk radio. I still have one college radio station with full time jazz programming, but after that, it's up to my collection and what little live stuff is happening around town.

Chicago, which once had a justified claim to being the center of jazz, has now rejected it. Change isn't always for the better.

Stuff That Makes Me Go Hmmmm

Stuff That Makes Me Go Hmmmm

Economist Richard Florida's 2002 article, called "The Rise of the Creative Class: Why cities without gays and rock bands are losing the economic development race." Basically, Florida argues that "lifestyle amenities" like a cultural scene and diversity makes some cities more attractive to creative people who build economically successful enterprises than other cities that lack these features. Fine, I accept this, especially since Florida bolsters his arguments with impressive charts and metrics. I should also add that the "lifestyle amenities" argument is taken very seriously by cities like Sioux Falls, where JA & I were told that the addition of an arts center helped the local industries and hospitals attract quality personnel away from major metropoli.
