Pioneer m90 and c90
Another NO here. 
"And now for something completely different":
Wow. A well known University that turned out a lot of famous graduates rediscoved an old toy. 
Affordable 300b Replacements
I don't have any recommendations, but be careful with some of these newer 300B tubes. Some of them draw a lot more amperage for their filaments, than the real original 300B design tube did. Some have other specs that may not work in your amp eithe... 
toslink/s/pdif fussy
A little more. Your source may a little time lag on the optical out, in comparison to the coax out.Or, your DAC/Processor just may identify the coax easier than it could an optical signal. If your source is powered on first, I would guess it may w... 
toslink/s/pdif fussy
Also, there may be a short delay in the order the D/A search for a signal at turn-on. The Toslink jack your using may be the first one in the search sequence. The other inputs may be checked for a signal after the jack your using is found to not h... 
toslink/s/pdif fussy
Maybe if your source is not giving the signal when your D/A, or whatever is turned on, it may start looking for another source that has a signal. It may rule out that jack as not having its signal. If the source is on first, then the D/A may lock ... 
Resistor to tone down tweeter?
A variable wirewound potentiometer could be used for this, but, they can add noise. A lot of speakers had variable line level potentiometers, and they seemed to have faded away in the majority of hi-end speakers.Hifitime Oops. I shouldn't have sai... 
Resistor to tone down tweeter?
03-17-12: PaulsaxStupid question for you electronics boffins. on a guitar if you want to roll off the highs you use your tone knob which uses a capacitor fromt he tone pot to ground (I think). Why would this not work in this case. Suspect I'm miss... 
Resistor to tone down tweeter?
First of all, make sure the tweeter is OK. Both channels should sound the same. A damaged voice coil, or something else in the tweeter can cause this.If you find both tweeters to sound the same, maybe your sensitive to their resonance (usually rig... 
Sub Integration Question / Recommendation
When both the mains and the sub were all turned on, something unexpected happened: the SPL level dropped down to just below 64 db. I had expected it to be the same or higher. What’s going on there? A lot of people set sub levels different than oth... 
Tube Amp Kits
Audio Note. I haven't built any of theirs, but they should be decent. Link.[http://www.audionotekits.com/] 
Can a variac be used to maintain constant voltage?
With your voltage only varying by around 1-2 volts, plug your amp right into the outlet. I would love to have my voltage stay that close to 120 volts. Mine will vary up to five volts, and sometimes more, the same same day. I live in a straight res... 
Speaker Wiring
I think the extra amp with its own volume control like mentioned, would be the best solution for your setup.I personally haven't heard these myself. The model 100 seems to have been around for a long time, and seems to be liked. The model 102 is s... 
Turntable hum problem after demagnetizing
Also, make sure a wire didn't break off inside your interconnects RCA's ends. 
Turntable hum problem after demagnetizing
One thing I just thought about is if the unit was exposed to a cold temperature, maybe moisture condensation formed inside it, shorted it, and passed enough voltage to the coils to damage them. I don't know its full design, but this sure seems pos...
