| Right Channel dropped out Bryston BP-26P (upgraded from BP-25P) Look into the RCA and XLR connector jacks with a bright flashlight to make sure nothing is stuck in there. To me this sounds like the right channel is shorted to ground. If nothing is in there, then the unit has to go back to the mothership. | |
| Tube Power vs Solid State Power Not true because amplifiers do not put out power to the speakers -- speakers consume power. Amplifier power output is the dissipation of heat. To simplify, if a speaker presents a 4-ohm load to a 12-volt ac signal, the speaker draws 3-amps from th... | |
| A/C power line polarity on new phono preamp I'm pretty sure that switch is for signal polarity, not AC power. | |
| Mono solves all Red and blue fuses mixed will give you purple fuses. No need to spend money on purple. | |
| Mark Levinson 5805 underpowered? You may have to adjust your volume and taper settings in the set up menu. | |
| Why are there no tube televisions anymore? Well done, OP, well done. | |
| Lower voltage caps If the DC voltage across the cap at all times is below 400VDC, then yes. Otherwise no -- the cap will stress out and turn into a wire or an open in the circuit. And maybe burn and create a mess, ruining everything around it. | |
| Why so many tubes? Power from an amplifier is dependent on three things: the gain of the input signal, the voltage at the output, and the power dissipation of the output devices. The more output devices there are (tubes or transistors) means the more power can be di... | |
| How hot is too hot? You have to measure the temp of both heat sinks under the hood with an infrared thermometer. If one is much hotter than the other, then it's a problem. Heat sinks shouldn't vary by more than 5 to 10 Celsius. If both sinks are the same temperature ... | |
| Aged components / service!? I have a CAT SL1 Signature preamp that I have been using every day for the past 28 years. Couple of years ago I measured the caps and all were to spec for micofarads and ESR.So the answer is... it depends. But for the most part, preamps do not gen... | |
| Dedicated 20a lines, 125 feet distance, which gauge wire to run? 125 feet is quite a long run and you should consider using a subpanel. Even with #8 wires you will lose 3 volts at 15-amp draw. A subpanel with minimum #4 wire will limit voltage drop to a little over one volt at total current draw of 15 amps. Fro... | |
| Are all amps being built wrong? The answer is economics. Amplifiers are voltage sources and practically all speakers are designed around being powered by a low impedance voltage source. Change the output impedance of an amplifier and then it sounds better with some speakers and ... | |
| Audiophile Fuses - Are We Certain They Provide Protection? The easiest way to test a fuse is to measure the voltage drop across it at different current increments (fuse resistance increases with temperature). If the voltage drop stays linear for currents up to and slightly above the fuse's current rating,... | |
| Cary V-12 blowing capacitors The problem is most likely a manufacturing lemon. Somewhere in that amp either a tiny section of insulation has been damaged, a small piece of wire or lead clipping lodged in a very inconvenient spot, or the wrong value passive component has been ... | |
| Class A Power in A/B amplifiers? No. Because there is no standard on what type of output stage to use. The bias current is set to give the best performance for the type of output stage in terms of linearity and distortion, while keeping an eye on the power dissipation (heat sinki... |
