| Power Cords Snake Oil ?? Nobody has considers what is behind AC wall receptacle and what kind of power is coming to that receptacle through the wires. Even if you pull completely new 20A line from breaker box to your HiFi (which is probably most efficient thing you ca... | |
| Swapping Wilson Watt Puppy 6’s for open baffle Pure Audio Project Trio15 Voxative's With an open baffle, you want the room behind the speaker to do something. The reflections, if the speaker is properly set up in the room, are used by the ear to discern the source of the sounds it hears; IOW improves imaging and soundstage. | |
| Rectifier Hum ^^ I'm doubting the filter cap failure theory, but you might be on to something; on reading the specs on the 274b one of the claims is lower hum, provided the power supply is built in a certain way, which is to say a fairly low filter cap value fo... | |
| ATMA SPHERE SCHEMATIC for a UV-1 M/M....... FWIW, yesterday I discovered that my employee that builds the UV-1s had taken interior photos of the early handwired units on his phone. The photos were clear enough to suss out the layout, so I sent one to Will. | |
| Joule Electra question If the tape output works, it is quite possible that the line stage isn't simply because of a bad tube. Give Rich as call as previously suggested (Rich is a great guy), (315) 622-4137; he may be able to advise you on that. | |
| ATMA SPHERE SCHEMATIC for a UV-1 M/M....... autospec can you elaborate on what required fixing on your MP-1 that cost 2k? I'm in the market for a used MP-1 and would like to know what might go wrong.Will found what was apparently the 3rd MP-1 ever built in a shop near his house. It neede... | |
| ATMA SPHERE SCHEMATIC for a UV-1 M/M....... Will, I was very clear about this on the phone. Who are the 'others' that 'don't see it that way'?It seemed quite clear on the phone that you were interested in doing this yourself, and you've made it clear to me in past phone calls that you have ... | |
| Amplification for Wilson Audio Sasha on the cheap Again, despite the low impedance at 80Hz or so, the speaker is easy to drive. We got walloping bass using our MA-1 amplifier which is an OTL, which are not known for driving low impedance loads. So if you have 100 watts of good quality, tube or so... | |
| ATMA SPHERE SCHEMATIC for a UV-1 M/M....... We have schematics for the M-50 and MP-1, Will. You asked for a schematic, not internal layouts. We don't have a schematic that is all that neat as I mentioned before. But apparently even if I had provided it, that would not have solved the proble... | |
| Swapping Wilson Watt Puppy 6’s for open baffle Pure Audio Project Trio15 Voxative's Having heard the PAPs, I can't say that they have any lack of punch! That seems to have a lot more to do with the amps driving them. | |
| ATMA SPHERE SCHEMATIC for a UV-1 M/M....... We simply don’t have schematics that look at that good for public consumption.As some of you may know, the UV-1 is based on the mods/updates we would do to a Dynaco PAS-3.So the phono stage is very similar to that of the PAS-3. The differences are... | |
| Is powerfull Amps only for low sensitivity speakes? May I ask your comments also for the difference between single ended triode amps and push pull tube amps in terms of 2nd and 3rd harmonics capabilities.Its not as simple as that might sound! SETs tend to make more of the 2nd harmonic than any ot... | |
| Tube preamp for Pass Labs XA-30.5 We have a good number of customers with Pass Labs amps, so I can say with confidence that if you go that route it will work fine. The MP-3 has no worries at all driving input impedances much lower.I think the big differences you are likely to hear... | |
| Rectifier Hum If I recall correctly, the tube rectifier in your amp is bypassed with a solid state device as well. This is making me wonder if its snubbed properly. If not, it could certainly contribute to hum. Tube rectifiers on their own don't need to be snub... | |
| Class D is just Dandy! George, its more complex than that.The reason Technics is switching so fast is to reduce distortion. The filter has little to do with it. At their speeds, the inductance of the speaker is sufficient. So their filters are mainly concerned with pr... |
