| Small gauge ground wire, is it OK? Wire that's rated for 15-amps must have a No. 14 ground and wire rated for 20-amps must have a No. 12 ground. Eldartford, even though you are correct that no current flows through the ground, it's purpose is to act as a secondary path back to the ... | |
| How to determine high current amplifiers Don't worry about current and voltage. Look for your target watts per channel into 8 ohms. Then see what the power is at 4 ohm, and, if given, 2 ohm loads. If the power increases considerably with decreasing loading, then the amp is powerful enoug... | |
| Accurate vs Musical All speakers lose their ability to be accurate once placed in a listening room. Early reflections, modal nodes, etc., all play a part in reducing the realism to a certain degree even if the speaker is 100 percent true to source. Also, IMO, a more ... | |
| How much current? 1. Dedicated lines are a good investment and will provide a benefit in terms of minimizing power anomalies from other users and less noise from things such as light ballasts, switching power supplies (computers) and household motors on the same ci... | |
| High priced power cable what about the romex Your power cable can act as an antenna that picks up noise from magnetic fields and radio interference which is all around. If the power cord is shielded properly, then it will minimize the introduction of noise from these EMI/RF fields.It does ab... | |
| Speaker Distortion or Room Interaction ? And while we're guessing, what is your idea of an "upgrade"? | |
| 20 amp dedicated lines Are the amps new? If so, I would either try another amplifier or let the JC's warm up for a few days and see if there's a difference. The JC's takes a while to settle in. If it's not the amps, it may range from something trivial like out of phase ... | |
| The Clever Little Sharp Hell, I've seen posts here that debated things like the effect of receptacle wall plate material. So why is THIS causing sacrilege? Because it defies common sense or knowledge? My common sense once told me that an "EMF sponge" is nonsense. Yet I s... | |
| Filter capacity in 2A3 amps In a 2A3 amp, the mains voltage is stepped up to a range of 250 to 350 volts, which means a load current in the milliamps to provide the output power of about 2 to 5 watts. In solid state amps, the voltage is stepped down to about 30 volts and the... | |
| condo owners, how do you appease the neighbors? Unfortunatley, there is little recourse on your part. Your are considered the "neighbor from hell" to the downstairs tenant. He has options such as initiating a condo board hearing or a noise abate lawsuit. Both can make your life miserable. Apart... | |
| Why outlet makers warn against aluminum wires? It's more than just oxidation and "cya". Aluminum and copper wire connections can cause arcing which can lead to fire; they need a special crimped connector, which completely encases the interface, to safely join them. The manufacturers of outlets... | |
| hum from nearby high-tension wires? Another possibility is the university complex itself is the source. There are probably large motors for air condioning and elevators, some of which may be variable frequency drive, that puts noise in the power grid. Another possibility is that the... | |
| Tube Break-In sound character change You replaced 2A3's with 300B's??? I dont' think break-in is at issue here, but compatibility. | |
| THE POINT SYSTEM OF WAF. You earn enough money in a month to buy any tube amp or big gaudy speakers - retail (+1,000,000) | |
| CLASS A AMPLIFIERS Generally, they are not more powerful. Class A designs are extemely inefficient because it requires that a lot of heat be dissipated to maintain stability, robbing power to drive speakers. For technical as well as practical reasons, this limits th... |
