Hi - I don't have a cable suggestion, but I did find out why the stock cables are so bad and why people are having a lot of problems with them. Below is a badly lit image of the stock cable, cut about four inches from the input connector. What at first looks like a bare copper shield and three...

The Tripath amp's outputs are configured in an H-bridge. There is no ground. If you measure the "black" output w/r/t the chassis, you will see that it is quite active. If you connect the two "black" outputs from the Teac together at the common ground connection of a female headphone jack, you...

Quite a lot to chew on here. Quote: Current can not pass back to the line through a broken amp It most certainly can. The primary side of your transformer shorts out. Is the amp broken? Yes. Is it still pulling current? Yes. Do you have a potential fire hazard? Yes. Quote...

Quote: Originally Posted by eyeteeth So what's the deal with the fuse in the back of my amp? Is that not designed to protect it? Sort of, but not really. The fuse is really there to protect the rest of the world from your amp. If something breaks on the inside of your amp such...

Try pressing straight inward half-way up the cone at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock positions. If the voicecoil is misaligned, you will likely hear rubbing in some positions and (maybe) no rubbing in others. If such is the case, your voice coil is probably misaligned. The...

I've used a product called Cramolin for quite a while, been very happy with it. It comes as two liquids - a cleaner and a finishing film. Use the cleaner first to remove metallic oxides and then apply the finishing film. The film is non-conductive and spreads out to a VERY thin layer; the idea...

Some of you are interested in modifying the Sonic Impact "T-amp" for better performance. I don't have an amp to play with, but I have a lot of experience with the Tripath parts used in them. Some suggestions and what-not: 1. Do not modify anything around the output pins of the amplifier chip...

I can tell you that the Atoms are a very good match for the Class-T part. The Atoms' efficiency is such that you will to fill an average sized room with sound. The Tripath amp has a low output impedance and can deliver high instantaneous current levels (6-7 Amps), so bass is full and...

Do the sofa shakers have their own amp or are they sharing an amp with something else? Reason I ask, it's going to be very expensive to make a passive half-octave bandpass filter in the 20-30Hz range if it has to pass speaker current. The Harrison FMOD is only for line level signals. It will...

I have to disagree with you on a number of points, Wolffy. Quote: Originally Posted by Wolffy The grunge that you hear along with your musical information is attributed directly the amount of RFI that is both external and internal to your system. The FCC's radiated EMI test...

All your power cords are carrying the same "signal" and are in phase. I doubt that this will introduce any audible problems. If someone suggests that it will, ask them to explain to you how they have their electrical service entrance wired, as the circuit panels on most residences will make your...

Quote: Originally Posted by gundam91 Are you sure? I think you are confused with the operating voltage of the amp itself. 220V-240V for most Europe, 110V-120V for North America. These tubes operates at 6.3V. The plate voltage on the tube is what he's referring to (correctly). The...

Audio amplifiers often use negative feedback to correct errors in the output signal. The output signal is compared to the input signal and the differences are fed back into the input to correct the error. If the signal is low enough in frequency and the feedback loop is fast enough, the error is...
