| 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? | |
| Amp and speaker matching. 86 db means that you will generate a SPL of 86 db at 1 meter with 1 watt of power.It is easy to get confused about this! In this case the spec is Sensitivity, not Efficiency. Sensitivity is 2.83 Volts at one meter, meaning that with a 4 ohm load t... | |
| interesting phenomena in the cutting room Hi Peter, what we have found about that pesky RTA is its not really a standard. The problem is variance in the cutting stylus. Under the scope they all look a little different, and to get them to behave you have to adjust the head up and down a li... | |
| Surface noise Davide256, so did I, from 1974 until now... but I was not discrediting your comments, FWIW. Simply adding to them. | |
| Oil For Nottingham Spacedeck? I should point something out here. The main deal with the oil is to prevent the bearing from failing. I have heard rumours that some manufacturers use the oil to produce drag on their drive system so that their speed controls will work properly. I... | |
| I think my speakers are killing my amps. Mcintech makes an excellent point! Check your fuses with a DVM. | |
| AUDIO RESEARCH-WHERE ARE THEY GOING I've known Kalvin Dahl for over 30 years. And Warren Gehl, Doug Wright... they are part of the core group of audiophiles that I hung with for literally decades and they are good people. I've known other people there for 20-25 years and I have a gr... | |
| Surface noise Davide256, you missed one- design of the phono section can affect ticks and pops quite a lot.Bdunn, the first thing to do is to determine the value that you need. There are several ways to do that, you could get a stereo potentiometer, wire it as ... | |
| I think my speakers are killing my amps. The VMPS is not particularly capacitive. Ribbons in general tend to have a fairly resistive quality so other than impedance they tend to be easy loads. | |
| Preamp for Atma-sphere s30 Thanks Marty. We can update those older S-30s so we can get them to sound just like the current version. If we do that the warranty reactivates. | |
| Surface noise Grados don't seem to like excessive tracking forces. I would not go above 1.7 grams.As per loading. There is a lot of discussion about loading MC cartridges (most of it bogus- loading MC cartridges is all about energy at RF frequencies rather than... |
