| adjustable "fixed" bias amps Sounds to me that's for both tubes and the bias is measured at the power supply takeoff. | |
| Dedicated line: 10 gauge solid core or 8 gauge stranded On the 10/3 romex, I do not use the bare copper grounding conductor; I cut it flush to the jacket at both ends. Use the red wire for grounding to the receptacle screw and the panel ground bus (don't forget to wrap the red insulation with green ele... | |
| Does the first reflection point actually matter?? Eric:Try the "Circling Tones Test" with and without the first reflection side wall panels: https://www.yarlungrecords.com/sonorus/ In my room, the sound is a full 180 degrees with the GIK panels and a little less without. Noticeable. | |
| Dedicated line: 10 gauge solid core or 8 gauge stranded I use 3 wire 10 gage Romex because the wires come pre-twisted. This goes a long way to reducing common mode noise being picked up from the EMI producing computers, routers, modems, iphone chargers, alexas, etc.If the circuit wire hot, neutral and ... | |
| Isolated ground for 20 amp Receptacles with isolated grounds are still grounded. The ground is isolated from the grounding system downstream of the panel. For example, if you install a receptacle to a metal receptacle box you tap from another circuit, the grounds are common... | |
| Thiel Owners As a Thiel 3.6 owner for over 25 years, I'm considering replacing them with either the 3.7 or 7.2. Found a pair of CS7's that were converted to the 7.2 but the cement baffle has a horizontal crack from each side of the midrange to the edge. Is th... | |
| Schiit Yggsdrusil - with New Unison USB My two cents is Yes. Prior to the Unison the Yggy sounded slightly better through my Theta Data Basic with RCA than the Aurender N100H and USB. With the Unison, the differences vanished and I prefer the Aurender/USB. The real improvement through t... | |
| Why are there so many wooden speakers? If a speaker weighs as much as a duck... it is made of wood... and therefore... a witch! | |
| 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... |
