| Need understanding on amperage Tonywinsc, that music has such transients and that a stereo needs either very high power and/or efficient speakers to reproduce those transients is not a matter of debate.What is a matter of debate is the math. Its more than just the current ratin... | |
| Oil For Nottingham Spacedeck? It doesn't foam up and lasts a long time. For turntables and tape machines its about as close as you get to a universal lubricant. | |
| Tube Preamp Paired with Tube Phono Stage? This is almost as frustrating as John Curl's JC-3 phono preamp offering only one impedance setting of 100 Ohms for MC. That one I'll never understand. The reason is if the preamp is resistant to RF at its input, the load on the LOMC is not critica... | |
| are some phono stages more resistant to hum? To clarify my comments, phono carts are ISOLATED devices, but are not inherently balanced. A true balanced voltage source would produce a symmetric V+ and V- signal referenced to common.A common method I use to identify a balanced source is what h... | |
| $$$Sensitive Speakers with $$Amps? Our amps only have one stage of gain. Hard to get simpler than that. In general its been my impression that cost is less important than the simple fact that some amps sound more like music than others. So my answer is now 'depends' as there are ex... | |
| are some phono stages more resistant to hum? You have to reference the input voltage to somewhere, and for phono inputs its the shield (-). If you could get a cartridge with a true balance output (like a center tapped transformer), with the split (or center tap) connected to the analog groun... | |
| Looking for the BASS THe lowest note on a Fender bass is 42Hz!Who are you trying to impress???Me. (organ pedal tones and synthesizers can go to 16Hz) That is who does most of the listening to my stereo. But I don't have subwoofers, instead I have speakers that go to 2... | |
| $$$Sensitive Speakers with $$Amps? The short answer is yes. If your speaker is high efficiency, you can get by with less power. Tube power in particular is expensive so this can have a huge effect on the price of the amp. | |
| Preamp or power amp has more impact to resolution? Chuck is right, if the source and preamp are unable to deliver the goods there is nothing you can do about it downstream. | |
| Need understanding on amperage Seriously, is anyone suggesting that the output section of this amplifier can deliver 3600 watts even briefly?? The output devices would be destroyed. Now if you assume a 4 ohm load rather than 1 ohm, the power is then 14,400 watts. Obviously this... | |
| are some phono stages more resistant to hum? Rtilden, just FWIW, tubes are no more prone to picking up noise from lighting than transistors. That is a power supply problem, not a tube/transistor problem. | |
| Tube failure -- what would happen in worst case? Cathode to anode shorts are very very rare, and the sort of thing that should blow a fuse without damaging anything else. If not, the manufacturer has not thought things through. I leave tube equipment on all the time. However, its tube equipment ... | |
| Need understanding on amperage To clarify: The 60 amps figure of the amplifier is not how much current the amp can produce driving the speaker. If it were, we could apply the power formula, which is that Power equals the current squared times the resistance of the load.So if we... | |
| Speaker Cable Different for 8ohm vs 4ohm As four ohm speakers go, Maggies usually have a fairly benign curve and are usually not that hard to drive.All other things being equal, if you have a 4 ohm speaker and an 8 ohm speaker, you will always find the speaker cable to have a greater eff... | |
| I think my speakers are killing my amps. How does the amp behave if there is no speaker load? |
