| External Linear PSU for Router - Voltage/Amps? I should have added: There was a case, the only one I know of, for a Chord portable DAC, that the device relied on a low amperage to protect the charging rate of the batteries. IMHO, a bad design choice made against convention. | |
| External Linear PSU for Router - Voltage/Amps? Match the voltage, excess Amps is OK. For instance: 12V, 8 A is just fine. The reality is a lot of nominally 12V linear supplies may provide slightly elevated voltages when unloaded, so you may read say 13.8V on a multimeter. That's fine, and e... | |
| Why Preamps Thump on Turn on @atmasphere Wow that is some serious entitlement there. I’ll get to it when I get to it. I had time then, i don't right now. Sit and spin until you cool off. | |
| Find the Problem If it hardens in the same place regardless of volume it's the TT/Cartridge. If it only hardens after turning the volume control to a certain point it's more likely to be the amp. | |
| I guess I need a new multimeter. You could also have bad leads, by the way. I like Fluke but goodness they are expensive. Often on 20% off at Amazon during holidays. | |
| Audiophile grade passive impedance buffer I should add that otherwise, imhifiman is correct. An impedance buffer is the solution. You'll trade impedance for gain, but at least it should ensure a flat response. | |
| "The Art of Speaker Design" by Lynn Olson Good points all, Hilde45. When I make a speaker, always for myself, what I care least about is pulse coherence. I’m sorry I just have never ever heard a problem which this solved for me. I have heard pulse-coherent speakers with a frequency respon... | |
| Audiophile grade passive impedance buffer Question is whether your preamp's output impedance is resistive or not. If it's resistive and your amp's input is also resistive you'll at worst suffer loss of gain. If it's a tube pre with capacitor outputs chances are it's capacitive and outp... | |
| Why Preamps Thump on Turn on @atmasphere Thanks for the follow up... I'll have to go take a look when I have time, which may be a while. | |
| How do I discharge the capacitors in my PS audio P20 ? Shorting a high uF cap directly is a bad idea. You can in fact ruin an otherwise good cap. Also, worth noting the voltage rating on a cap. If it’s 50V say or less, it’s not that dangerous. If you don’t have a 10W resistor, just use a bigger Ohm ... | |
| Do You Have to Play a Component to Warm it Up? Vlad urged that users leave it on all the time -- though I don’t like running tube gear when I’m not home (and I used to pull power during electrical storms). That thing did not sound right for a long time from a cold start. @whart - It's weir... | |
| Do You Have to Play a Component to Warm it Up? Really, @erik_squires? My Lamm SETs like to play 45 minutes or so before they come on song. Ditto, my other tube components. Hi @whart - I stand corrected and informed! Thank you. I’ve not used much tube gear I’m afraid. The worst case of w... | |
| How do I discharge the capacitors in my PS audio P20 ? You culd also just unplug it and wait 24 hours | |
| Active Speakers Don't Sound Better You will not understand this and I draw your attention to you claiming, in a previous discussion with you, that if a bigger inductor of the same value replaces the original in a passive XO then the lower resistance of the new bigger inductor shou... | |
| Plugging rear ports of "bookshelf" speakers? Think of plugging a port as a tuning option. The options lets achieve good bass in a variety of situations compared to a speaker that did not have a port. @noromance is correct, you ARE altering it's sonic signature so that it sounds better in w... |
