| I am at the end of my rope, please help From the last set of measurements, it sounds like the arm wiring is fine.OK- so with 2 different cartridges the same thing happens. And if you swap the cables from the tone arm left for right at the input of the phono section, the problem moves. A... | |
| Who is the KING of MONOS? Dev, the MA-3 has 42 power tubes in each channel. Since they are dual triode tubes, that's 84 tube sections.The amp has built-in automated bias and DC Offset control (the tubes are directly-connected to the speaker outputs), built-in AC line regul... | |
| I am at the end of my rope, please help Audioraider, the measurements you described indicate a problem with the tone arm cable. The center of the right channel RCA should have continuity to the red lead, ground of that RCA has continuity to the green lead. They should not have continuit... | |
| Empire 298 Questions We have developed an update path for the Empire as well (and Mike is one of our customers...) http://www.atma-sphere.com/products/208.htmlIf you decide to do the work yourself, we also have new correct motor mounts and new belts. This is an easy t... | |
| How close to the real thing? That's true but they are listening for the notes, not the sound. Its an entirely different portion of the brain that is used. Try sitting in front of a keyboard and see if you can work out the notes of a favorite melody and you will see what I mea... | |
| Who is the KING of MONOS? Why no tubes? Can't stand to be in the sight of the King?http://www.atma-sphere.com/products/ma3.htmlI've yet to see a transistor amp executed at this scale. Have I missed something? | |
| What's more important, watts or capacitance? I don't listen at real high volumes, but I do like classical music at close to live levels.Classical music can get to 115 db in the first 5 rows of almost any concert hall. To do that with your speakers will require over 1000 watts.A nimble amplif... | |
| Rectifier tube keeps blowing Sounds like a bad filter capacitor to me. | |
| Rectifier tube keeps blowing Devilboy, try starting up the amp with no output tubes in the sockets. If the rectifier blows, your filter caps are shot. Its a hellava way to find bad caps IMO, but you would know for sure.The fact that it did this before and after power tube rep... | |
| Help needed to diagnose preamp channel unbalance. So replace the volume control already :) this is a classic volume control-related symptom. Nothing to do with tubes... | |
| Rectifier tube keeps blowing I would not be surprised to find a bad filter capacitor in the power supply of this amp.However, you did offer a clue to an alternative explanation:You just installed a new set of 6550s in the amp. Did the rectifier by any change begin blowing aft... | |
| ZU OMEN speakers 12ohms?? The ZU speakers seem to work better with amplifiers that have a slightly higher output impedance, and the newer models seem like they are more accurate/less forgiving of brightness and sluggish behavior from the amp. So yes, some amps will be reve... | |
| vintage amps Do you mean the really unstable one that was hard to keep running? | |
| Resolving amps IME Maggies are easy to drive if the amp is alright with the load. A lot of tube amps can do the job other than this. So if you want a tube amp, often you can use a set of ZEROs http://www.zeroimpedance.com and do quite well. Sixty to eighty watts... | |
| Why no remote controlled discrete resistor volume? Mitch2, your experience is correct. There is no way around the fact that you have to control the volume; the more revealing your system is the more you have to make sure that the volume control is not messing things up. You can get the control out... |
