I need some help with power in my home! You really should call an electrician. I'll bet a nickel it's one of two things: the service ground lost integrity; or... if you have aluminum wiring, the lugs at the panel and breakers need to be deoxidized and re-tightened. | |
Bypassing Caps - what is it really about? Bypass capacitors in crossover circuits are, in my opinion, useless. The reason bypass capacitors are used is to lower the overall impedance at frequencies where the equivalent inductance of capacitors has the dominant impedance, which is above th... | |
diffuser or absorption panels, which would you choose? That’s the wrong approach. You first have to identify the problem before implementing the solution. The first step should be an analysis of the listening room. Acoustic companies offer that service. Best to contact them directly. | |
Quad panel outlet - can I do one circuit on this? Yes, you can do it. Wiring one quadplex outlet on one branch circuit is the same as two duplexes on one branch circuit. The quad give you the convenience of plugging everything at one location and, more importantly, at one ground point. A dedicat... | |
Why don't higher end amplifiers come with a separate power chassis? A big reason is warranty servicing. Connection points are a leading cause of failure due to the mechanical stresses on the coupling and the connecting and reconnecting cycles, so there has to be a large benefit to cost ratio (and with a power amp ... | |
Isolation transformers output voltage higher than wall What are you measuring with? There could be as much as a five to six volt difference between true rms multimeters and averaging multimeters when measuring wall voltage. All multimeters are accurate with a clean sinewave power but not with wall vol... | |
What are your top three favorite classical compositions? Schubert Symphony 9 Beethoven Violin Sonata No. 5 Mahler Symphony 9 | |
Insulation between floors - how affective? Check first that this isn't a routine maintenance issue. Noise from circulating water could be air in the baseboard piping. You'll need to bleed and fill. Rumbling noise from a boiler could be a restriction in the chimney or flue, caused by soot (... | |
Still another question about biasing tube amps Both the tube type and the amplifier topology (Class A or A/B). To keep it simple: it's maximizing power, minimizing distortion and maximizing tube life. From there the bias is a function of the plate voltage and impedance of the OPT primary. Whe... | |
Driver Testing - reduced output Use a multi-meter to measure the resistance across the speaker terminals. Normally, the resistance should measure around 3 to 6 ohms. If both measure exactly the same in this range, it's probably not the crossover and instead a driver issue. | |
I have NOVA V's and I am not happy Could also be the Sonus Fabers are reproducing the recording with all its warts. I have the same issue with my Thiel 3.6’s. On great recordings they are unbeatable; on poor recordings the performance better be great for me to tolerate. If you’re ... | |
Custom Tuning Conspiracy The reason such a speaker company doesn’t exist is because there is no business plan or marketing for such a product. Or in plainspeak: it won’t make money. The main reason it won’t is because the consumer does not know a Thiel-Small parameter fr... | |
DC entering my amp? What I would do is check for DC offset at the speaker terminal outputs. Set a DMM to DC Volts and measure across the speaker cables at the amplifier binding posts with the amp on (for at least 5 minutes) and everything connected as normal, all on.... | |
Alta Vista NP-100 schematics? There are things you can do in a pinch without a schematic. I would disconnect the output transistors on the same channel with the diode and with a multi-meter check the resistance across the pins. A shorted transistor is a common cause of burned ... | |
Wiggle kt170 base Unless you swap the tubes in both sockets to see if the hiss stays with the tube or the socket, there is no way of telling if it is a bad tube or a bad mechanical connection. You could have a bad tube and it decided to show itself that day. Or you... |
