| Two physical grounds?? Sorry, my mistake and no offense taken. I assumed you had grounded outlet boxes. Most 2-prong receptacle wiring in older houses that I have seen built since 1960 is armored steel BX (with ground) and the outlet ears against plaster so installing a... | |
| Two physical grounds?? The solution is easy provided you have a metal outlet box. Simply buy a 3-pronged outlet and a package of green ground wires (pre-looped, and with green screws, called 'Equipment Bonding Jumpers'). Remove one of the old two-prongers where you want... | |
| Replace pwr cord w/IEC socket on vintage gear? If that Heathkit is a tube amp without a protective cage, you do not want a grounding power cord for the same reason toasters and lamps are not furnished with three-prong plugs -- live parts exposed from damage have no bond to earth. Also, the gro... | |
| Is the most efficient speaker the best speaker? The most efficient (sensitive) speaker primarily benefits the lowest power amplifiers... is the lowest power amplifier the best amplifier?If so, then what would be the purpose of manufacturing higher power amplifiers and less than the most sensiti... | |
| Best CD player under $25000. And I'm thinking of all those turntable setups at 1/10th the price or lower that may very well outperform some of those digital Ubermenschen. | |
| damping factor Actually, what happens is when the amp sends a signal to the driver it energizes the voice coil and causes the cone to move. When the signal stops, the woofer cone keeps moving by inertia (the amplifier cannot stop the moving mass). This causes th... | |
| Hum issue - driving me more crazy Bringing the cable above the floor may be moving them away from fluorescent ballasts. Speaking of lights, do you have any low voltage LED or decorative lighting that feeds off a DC transformer? These introduce DC into the wiring that get into grou... | |
| Hum issue - driving me more crazy Try lifting the grounds on the amplifiers by using a two-prong adapter. You have the perfect setup for ground loops -- all equipment plugged in multiple outlets spaced far apart on the same circuit along with interconnects running the length of th... | |
| "The Heat Pipes are coming"... The Heat Pipes are Heat sinks are rated in degrees c per watt. This means that the amount of heat dissipated is constant and that as the outside air warms, the device, too, warms to maintain the difference. Not correct. The term degrees C per watt is the thermal res... | |
| "The Heat Pipes are coming"... The Heat Pipes are You are telling us that removing heat = better sound. I am telling you that lowering the thermostat removes heat faster, increasing the surface area of the equipment case removes heat faster and increasing the conductivity of the equipment case re... | |
| "The Heat Pipes are coming"... The Heat Pipes are Good Lord... another fundamental law of science that is altered when audio equipment is involved. Heat transfer depends on basically three things -- temperature differential, surface area and resistance (thermal conductivity). These hp's affect th... | |
| Power line question I don't think you will have a problem. My guess is that each amp will consume about 300 to 400 watts each, maximum. That means both amps and a preamp in the same outlet will have as much of a power draw as a desktop computer, monitor and printer. ... | |
| High-end amplifier clarification? To me, "High End" always preceded the word "Audio" and not a specific component. You could take one of those half million dollar amps, hide it behind the curtains, and hook it up to a pair of $200 speakers and feed it from a consumer CD player and... | |
| How can a 40 watt amp outshine a 140 watt amp A 40 watt amp can out perform a 140 watt amp in two ways. First, a watt is current into a resistance, and the resistance is the speaker. But the speaker resistance varies with frequency. As the resistance offered by the speaker drops, the amp has ... | |
| wireing multipal outlets. Four wall boxes each with two Hubbell duplex receptacles? Use 6-inch pigtails in each box. Each wire nut -- one for black one for white -- will have 4 wires. It's easier IMO to use pigtails in ganged boxes. Also, pigtails are a better job -- reduc... |
