| Brentworth Type III It has been a few years, but I thought they were great sounding speakers. There wasn't any harshness in what I heard. Wait until they are broken in and go back.I wonder if the fact you hardly ever see used ones for sale means everyone that buys th... | |
| Outputs of 2 amps share common return - problem? I assume when you say return you mean the black speaker post?If the black post on both amps is connected to chassis ground then it won't hurt anything, but you could create a ground loop and some hum. You can use an ohm meter to check, just make s... | |
| PC as an analyzer You'll need a card and software. Do a google search and you'll companies like this. | |
| Need help finding out the Watt Value of a resistor Hook it up to a variable DC supply. Turn up the supply slowly until the resistor goes up in smoke. Use Ohms law (P=(VxV)/R) to get the power rating. Of course, that assumes you have one to burn :>) | |
| cartridge loading ? The cartridge acts like a curent generator i.e. it trys to put out the same current no matter what the load is.Using the equation V = I x R (voltage = current times resistance) it is clear that as resistance goes up with a constant current, the vo... | |
| Jazz Big Band Recommendations? I second the Dave HollandGinger Baker and DJQ20Carla Bley Big Band, I don't think much of the new one "Looking for America" but the rest are good, "Goes to Church" and "Live" are a few favorites.Joe Henderson Big Band | |
| Dummy Load Radio Shack has 8 ohm 20 watt resistors for $1.99 each that should work fine as long as you don't crank it up too loud. Just disconnect the speakers and put one between the binding posts where the speaker cables were. I don't know how much power y... | |
| XLR to RCA conversion You can certainly use an XLR-RCA adapter to feed your amp a single ended signal. Just put them on the input to the amp as Tvad says. However, you would lose the noise rejection benefit of the balanced cables. You can't have it both ways. The noise... | |
| amp pop - need help Contact McCormack, they should know. The audiogon home page has a link to manufacturers but here it is,http://www.mccormackaudio.com/service@mccormackaudio.com | |
| appearance of burn on 7308 Amperex tube You are probably setting the after effects of the tube's getter. This is an element that is burned in the last stages of a tube's production to get rid of any residual oxygen left in the glass bottle after it has been evacuated.If it sounds good, ... | |
| High Level Distortion I find it hard to believe that cables, tweaks, or room treatments would produce the distortion you describe. BTW, 88 dB is not very loud in real world terms so I have to suspect some faulty electronics or a blown driver in your speakers. Play at a... | |
| Anyone Blow a Release Valve on Power Caps? Actually, to get 600 watts into 8 ohms requires 100 volts across the caps, so they must be using a pair in series for each voltage rail. The voltage is additive but the capacitance is halved so you have the equivalent of a pair of 126 volt 41,000 ... | |
| Microzotl start-up filament flare? The reason is that the resistance of the filament increases dramatically when it gets hot. So when you first turn on the amp, the filaments are cold and there is less resistance to current, so a larger amount of current flows through them until th... | |
| Anyone Blow a Release Valve on Power Caps? A side note to Sean's post, the large "beer can" electrolytics such as you have in your amp all have a small valve (looks like a small rubber bump on the side where the wires connect) that will release the gases that form if the cap breaks down. W... | |
| Anyone Blow a Release Valve on Power Caps? Electrolytic caps blow because:a: they had too much voltage across them, i.e bad designb: they broke down due to some internal defect, i.e. bad capThe volume you play the amp at has nothing to do with it. Assuming a good design that doesn't put to... |
