12AU7 and related 9 pin triodes have a center tapped filament that can run on 12 or 6 volts depending on whether the segments are wired in series or parallel. In most amps they run on 6 volts as that saves having a special 12 volt secondary windin... 
Audiophile Staff
I read about a Japanese audiophile whose name I can't remember in Stereophile many years ago. He kept his audio collection in a dedicated 5 story building with many different systems on the various floors, and much of one floor devoted to LP stora...

Firing up old tube amps. Should I worry?
Electrolytic capacitors deform over time when not exposed to voltage. The oxide layer that forms the dielectric slowly dissolves. Capacitors that wee rated at 450 working volts when new might only be able to handle a fraction of that after 15 year... 
Older is better - D/A chip?
Audioengr--The Nyquist Sampling Theorem requires the use of a reconstruction filter to remove ultrasonic images of the audio signal no matter what dac implementation one uses. This filtering can be implemented either digitally or by analog circuit... 
Does fair trade still exist
Whether we call it price fixing or something else, it still represents an attempt by the manufacturer to disrupt free market competition among its dealers. Many manufacturers dread having their products become commodities and try to keep retail pr...
