| Grounding ? Bob_bYes I am paranoid, but that doesn't matter in this case.My personal system has NO hum or other internal noise issues.My recommendation is to check NOT to ground, but between system components. IF there is voltage present, I would consider swa... | |
| Amp damping factor? Al, isn't damping simply the instant ratio of speaker impedance and the impedance of the amp to the back EMF generated by the speaker? The amp, best case is a dead short (not possible in fact) to this back emf. Take a bare woofer driver and short ... | |
| Grounding ? Bob_RI believe your statement would be true IF there were no hot/neutral reverse wiring. I do NOT mean the outlet, the condition of which is easily seen with an easily purchased outlet tester, but internal to each piece of gear. Does that make any... | |
| Why manufactures don´t burn in their amps and ... here here | |
| Amp damping factor? A high 'Q' speaker will sound under damped even if the amp has a damping factor of 10,000 or more.Voltage source amps will have hi damping,Current source amps, not so much.I suspect that a critically damped speaker ('Q'= .707) will be good even wi... | |
| Why manufactures don´t burn in their amps and ... IF burn in were required, just think of the facility required.1 station with good power for each amp along with dummy loads appropriate to the power. One good power glitch and there goes a couple months of inventory....poof!The heat alone would pu... | |
| cooling my Krell monoblocks Classic.Thanks for tips on quiet fans. I may have need sooner than later.Also, your fan use sounds correct. 'Draw the heat out'.An annual cleaning / dust clog hunt may not be a bad idea, either. | |
| cooling my Krell monoblocks Again, I urge caution. ALL amps without fans as a designed in feature are passively cooled. The idea is that warm air rises and pulls cool air in from the bottom. Running under normal conditions in a 75f house, this should be enough. Stick kitty o... | |
| Grounding ? Is a possible fix, and this is JUST a question, that 1 or more pieces has an internal hot/neutral swap?Could you tell somehow? Maybe have all gear plugged into the wall without any I/Cs. Than measure for voltage between the chassis or ground of ea... | |
| cooling my Krell monoblocks All electronic lifetimes is lowered by heat. The only thing I know of that really likes heat, is indeed, the Cat.I had one sponteniously combust on me after it lay in front of a fireplace for a couple hours. | |
| cooling my Krell monoblocks First, be careful aiming a fan at Any piece of gear. IF you are somehow interfering with the natural convection (hot air rising) currents that the heating of the piece causes, you could actually make it run hotter, or too hot. Premium (read as HEA... | |
| Thinking of buying a solid state amp 'd' just like any other topology has good and bad examples.PF correction is used to help present a more resistive load to the power company. Large factories are penalized by the electric company when there PF drops below 0.9 or so, which is a mode... | |
| LETS COMPARE TUBE AND SS AMPS. TECHNICAL Watts is Watts, at least into a resistor, which NO load is, as far as I know.One major difference is the delivery of power into reactive loads, which to a greater or lesser extent includes ALL speakers. Huge phase angles at low impedance will take... | |
| Requesting input from iMac users Any reaction to I-mac -> Airport Express ->Toslink -> DA section on a CA840c?This is where I'm heading but maybe I'm heading for trouble? I am in process of putting everything on my confuser in 'Apple Lossless'.... | |
| Dramatic Visible? Power Issues -- What Next? Please be careful, if you decide to power up the old pre again. If this unit has sat unused for the 7 years since the original post, I'd take it to a shop and have them put it on a Variac to bring it up slow....I'm betting on a dried up cap. |
