what does a Rectifier tube do?
All AC powered audio gear uses rectifiers. They change AC from your wall socket into the DC required to run electronics. The "rectifier" is built from diodes. The diodes may be either solid state or tube (btw Mullard is a tube brand).There are dif... 
Audio Alchemy transport problem
Which Transport? 
Copy coding on Memorex
Garfish is refering to the Serial Copy Management System (SCMS) that just about all consumer digital audio products are required by law to support. There is a flag in the digital header for the music data (on CD, DAT, etc) that is set by the origi... 
How do you decide on new music to buy?
Down here in New Orleans we're blessed with a wonderful FM station: WWOZ. This station is volunteer based, not college affiliated, and plays a variety of roots, folk, blues, and jazz music. The various shows are done by DJ's who love the music and... 
Digital cable v. standard interconnects
No digital cable with RCA termination will exhibit true 75 ohm (nominal) impedance. RCA connectors were designed for audio rather than radio frequency (RF) use. They do not exhibit a constant 75 ohm impedance at the RF frequencies used by the digi... 
What is the future of amp technolgy?
Soix:I concur. One thing I forgot to mention is that "digital" amp technology is inherently energy efficient and relatively inexpensive to build, compared to classic big iron analog amplifiers.The executions of this technology will only get better... 
What is the future of amp technolgy?
To Twl:Like so many buzzwords "digital amp" has several meanings:1) A "switching" (aka Class D, Class H) amplifier in which the output stage at any moment is either fully conducting or fully off. This is unlike a conventional analog amplifier in w... 
Phase inverting preamps
The analog music signal input to your preamp is alternating current. The electrical voltage of this signal constantly swings between positive and negative in a manner corresponding to the musical information (I know this is an oversimplification).... 
What is the future of amp technolgy?
I also play some guitar as an alternate hobby (like I need one). In the guitar world tube amps rule, and are prized for their colorations and distortions. This is almost the polar opposite of the hifi view. In recent years various guitar amp manuf... 
tube amp/flutter in speakers?
Unless it's a rare output transformerless (OTL) design, your amp has an output transformer between the power tubes and the speaker. This transformer will not pass DC unless it is seriously defective, in which case you'd likely have more severe sym... 
What's up with Theta's Gen. 8 D/A ?
Trouble is, with the fast moving nature of Digital technology, by the time they introduce it it's obsolete! 
either DAC or transport is giving troubles...
Could also be a preamp problem - try a different input as well. 
AT&T ST to Toslink connectors ...
Glad Steve at great Northern could help you. Wadia actually made a companion piece to the 9 to convert inputs from coax, TOSLINK, etc to ST. It was an update from the similar box that was made for the Wadia 2000, and was designated the Wadia 10.I'... 
AT&T ST to Toslink connectors ...
I don't think you'll be able to stick an AT&T fiber into a TOSLINK connector. Even if you mechanically get it in the connector, the systems operate on different optical wavelengths.There are a number of jitter reduction devices (such as the Ge... 
Smoke coming from transformer means........anyone?
The Variac method doesn't work so well if the unit has a tube rectifier. The tube rectifier won't really conduct until the filament voltage gets close to specification. This point will be somewhere around 75-80 volts AC input. At this point you pu...
