| How long is the break-in time for a Sophia Electric Blue 6SN7 tube? Tubes gradually get worse with time. | |
| 120v vs 240v 240 volts allows for smaller wire sizes since the amperage draw is cut in half for a given amplifier power consumption rating at 120V. Since you are using #8 wires you are negating the main advantage going to 240V. | |
| Altis Reference DAC problem and Repair That is usually a symptom of a loose solder joint, especially around a transistor lead. The heat shifts the lead and it loses contact and returns after it cools off. If you can access the solder side of the board, go over it with a magnifying glas... | |
| How does the input impedance of an amplifier effect it sonically? That's a very good question. The simplified answer is that the resistor which sets the input impedance is usually sized the same value as the global negative feedback resistor in order to minimize DC offset from a gain mismatch between the two dif... | |
| System problem About that turntable... did you play through it to eliminate the DAC as the culprit? | |
| The Hardest Naturally Occurring Substance on Earth It's simple physics. According to my handbook for sound engineers, the contact area of the stylus is 0.2 millionths of a square inch. That means a tracking force of 1 gram (0.0022 lbs) divided by the contact area is 11,000 psi. That is way more pr... | |
| Mark Levinson 533H Amp fuse information May not be a fuse, could be the input coupling cap fried and there’s an open circuit. Even if it the fuse, send it in for service. You never can tell what else can be the problem and you want to make sure no safety caps were damaged, which could l... | |
| Going Price for Apogee Divas? That’s blue book trade in, not sale price. A dealer will pay 4200 for those speakers on a trade in and then put them on the floor for at least 30% higher, or $5500. Sellers usually research before they state a price. | |
| Seeking power conditioner recommendations / hum elimination If LED lights are buzzing that could mean those lights are on a dimmer made for incandescent bulbs. Those triac dimmers can put electromagnetic interference on your circuits causing both the audio ground loops and the lights buzzing. If they are n... | |
| Using 15 amp power conditioner and power cords with 20 amp wired outlet. If you install a 20-amp breaker, run a #12 or #10 branch circuit and install a Nema 5-20R receptacle, that will cover all 120 volt options for 15 or 20 amps.My advice: use romex 10/3. Cut the bare ground and use the insulated red for ground connec... | |
| Primaluna evo 400 - unmatched tubes It doesn't matter if the tubes are matched in the Prima Luna. The adaptive bias circuit sets the idle bias current of the output tubes by sensing a voltage drop across a resistor. That voltage modulates a transistor to either increase or decrease ... | |
| Educate me about gain and amp/preamp matching Look at it this way: assume two cars with the same engine are accelerated to 50 mph. The first car requires the gas pedal depressed 1-inch and the second car requires the pedal depressed 1.5-inch. Both have a different gain but both have the same ... | |
| Lumin or Aurender I have the Aurender N100H. The thing that most impresses me is that Aurender tech support can log into your player and correct software related issues. That is one reason, and a big reason, I am hesitant to seek out upgrades outside the Aurender p... | |
| Ever feel like a "low dollar" customer that your dealer doesn't think worth their time? When you tell a store you are an interested buyer IF they carry something you like, you are not seen as a low dollar customer. You are seen as a waste of time. A dealer has a product line. If you are interested in one of those products -- and make... | |
| Do Ethernet cable Cat8 DH Labs need burn in I 've had that cable now for 6 months and can honestly say that I have not heard any changes over that time. But it did make an improvement right out of the box compared to the Amazon cable it replaced. |
