cable burning
Al,Heat = power.....Wonder how much amp output power the thing consumes?Jim 
Resistor to tone down tweeter?
Mcpherson,Agree with the other posts.Just to add.....Make sure you have the speakers set up properly.You might try tilting the front of the speakers back slightly. That will raise the tweeters dispersion angle slightly above your ear level when si... 
Balanced vs standard power
Are you saying that by adding 220uf to the circuit I have effectively lowered my 10kVA xfmr rating to 5kVA?03-11-12: NormNorm,I agree with Al's explanation. Not sure why the manufacture shows 41 amps FLA for each winding instead of 41.67A.... 5000... 
Balanced vs standard power
Al,Just wonder if the poor PF, caused by too much capacitance on the AC line, is doing anything to the power xfmrs and switching power supplies of his audio equipment.You are the EE here.... What say you?Jim 
Balanced vs standard power
Good points, but in no. 2 shouldn't "lead" be "lag"?03-10-12: AlmargAl, You are correct.... Should read Too much capacitance causes the voltage to "lag" the current causing a leading power factor. Result is a low power factor.... Re the 220uf, tha... 
Balanced vs standard power
By adding a 220uf capacitor to the secondary side of the transformer,03-10-12: NormNorm,A word of caution when adding capacitance in an AC circuit. Two things that can happen.(1) The capacitor can raise the output voltage.(2) Too much capacitance ... 
Belt noise on my AR turntable
Took a close look at the motor pulley as well as the sub platter and sure enough there was a black grit residue on both where the belt traveled.I cleaned both with alcohol and wiped dry.Couldn't believe the amount of black junk that came off.I the... 
Dedicated Line
If your computer has an optical output, using that to your DAC could eliminate the need for a separate line for the computer, as there's no electrical connection through optical. 02-19-12: KbarkamianThe non linear switching power supply of the com... 
Dedicated Line
Best way to go is separate dedicated lines for digital and analog equipment.Definitely for a home computer.... They put filthy hash back out on the AC line. Dedicated lines decouple the power supplies from one another.Digital equipment switching p... 
Shielding components from EMI/RFI... Help please
Bryon,You might want to do some research on the archives of Tweakers' Asylum regarding the use of ferrous, magnetic, materials. There may be better ways to shield for EMI.Search shielding for EMIhttp://www.hottconsultants.com/pdf_files/ground.pdfh... 
IC Failure
Touch one lead probe of the meter on the outer shell of one RCA plug, the other meter lead probe on the outer shell of the other RCA plug. You should read continuity.Do the same test on the center hot pin of the RCA plugs. You should read continui... 
Shielding components from EMI/RFI... Help please
Almarg, I've always wondered about the code to use only one ground rod as well. I have never heard an explanation. 02-14-12: Sarcher30Sarcher30,There is no limit of the maximum number of grounding electrodes (ground rods), only the minimum require... 
Shielding components from EMI/RFI... Help please
Neither of those scenarios seems applicable to what Bryon was doing with the second ground rod, assuming that the means of insulation between the Reclocker and the Sonos and their grounded enclosures is sufficient to withstand the voltage that wou... 
IC Failure
More than likely the cable has an open connection.More than likely at one of the RCA male plug connectors.Bending the cable too sharply near the end can cause a connection to break free.If the ends are the type that can be disassembled, carefully ... 
Shielding components from EMI/RFI... Help please
Bryoncunningham,What's with the dedicated ground rod buried under the house?The earth does not possess some mystical magical power that will suck, drain, RFI to it.What you have created is a great path for a lightning strike to follow. There is a ...
