| VA vs. Watts? How much power do I need? Power cond Some power conditioners are rated in WATTS (PS Audio, Hydra, eg) and some are rated in VA (Equitech, eg).To size a power conditioner rated in VA: add up all the equipment power ratings that are given in WATTS and double that value. Add the (2xwatt... | |
| Are MOSFET's voltage, not current, devices? Transistors and tubes do not create voltage or current. They let current pass through them. The voltage that moves the current comes from the power supply. The current output is determined by the power supply voltage and resistor values around the... | |
| why does preamp improve sound quality? Yes, a preamp will add some distortion or cause the signal to "lose" something. But like any other active component the power supply, regulation and output devices will determine everything. A top-notch preamp will overcome any loss that occurs wi... | |
| Loose Veneer, best Fix? If only a little is coming off or fraying, you could first try an iron (set to low) and run it over the speaker with a few sheets of paper between the iron and the speaker. This may melt the glue an cause it to stick. This may be your best bet sin... | |
| Why "Cryo" anything? I'm no expert in MSE, but from what I understand is that the cryo process involves first heating the metal and then cooling it down to whatever cryo temperature. From what I've read, the cryo process used in tool and die manufacture results in str... | |
| Hum in system from interconnects??? What you describe is possible. By removing the I/C's from the preamp, the shielding path is broken and the I/C's pick up external RF and EM fields. If there's a loud hum, the amplifier is probably leaking a small amount of current to ground. You c... | |
| Power amp power draw questions What it means, simply, is that the 40 amps is the secondary current out of the amplifier's transformer. The primary side of the amplifier's transformer is:120 Volts input times 15 amps = 1800 (wall socket)...The secondary side of the transformer m... | |
| 4 Ohm Speakers, 8 Ohm Amps A 4-ohm load will draw more current from the amplifiers. The current may exceed the capability of what the transistors and output stage devices can handle during certain listening conditions. This can cause failure of these devices from excessive ... | |
| Isolated Ground Outlets Hosp Grade vs Audiophile PS Audio Power Ports are isolated ground. I haven't tried them so I can't say if they're better than the Hubbell I/G's that I installed in my former residence (my system was dead quiet). My opinion is that the isolated ground circuit will provide ... | |
| Degrade in sound over 48 hours. What happened? Substitute, if you can, another IA and cdp without the power strip into your system and see if the problem is duplicated to confirm a power problem. But I don't think it's an A/C issue...It's very possible it's the receiver (I'm assuming you reter... | |
| One SS amp running hotter that the other,. . . I would get it serviced. If an amp runs hotter than normal it can cause the transistor and other elements to fail. I agree that it's probably a bias fault caused by an open resistor, or a resistor that's drifted in value. My guess it's the emitter... | |
| Volume level mystery - can you solve it? Not knowing the speaker, I would guess the 2250 amplifier and speaker setup is running less efficient than the 85/140 biamped setup. With only one amplifier connecting both high and low drivers, the overall power consumption of the speaker to prod... | |
| Crossover definition Without getting into the theory, these are some generalizations without knowing anything about the room, the speaker type, the number of drivers, the driver's parameters or the listening postition:Use the Bessel setting for a better transient resp... | |
| did lightning do this? You may be able to get some help from your homeowner's insurance policy. Lightning damage of electronic equipment (which is what you probably incurred) is usually covered. | |
| Tube pre-amps: what defines "better" Generally speaking, the more a tubed preamp costs, the better the power supply. More often than not, the preamps' performance will depend more on the power supply and voltage regulation than the types of tubes it uses. Regulating voltage and provi... |
