| Debuzzing a Wheaton TriPlanar problem Dr_John, I think I did not read your first post all that clearly. Now the problem sounds to me like it might be a sort of RF oscillation in the preamp. I would not characterize this as 'feedback'... it sounds like either a very bad ground or RF in... | |
| ZU OMEN speakers 12ohms?? Mahughes, no, that is as opposed to the Druid.Afc, the ZU speakers are all fairly high efficiency. So they encourage the user to use lower-powered amplifiers if they can. An excellent example of this is the Definition, which is 6 ohms. A lot of pe... | |
| How close to the real thing? Shadorne has hit the nail on the head- commercial recordings are the primary barrier to making it sound real.If you were to take a set of good studio microphones and put them in a different room, away from your system, you might be quite surprised... | |
| How close to the real thing? We do have another issue- one which might explain why the headphones work so well:The original performance is always in a space with its own acoustic signature. The mics are always in that space too.Your room is not.So the idea that the musicians ... | |
| vintage turntables? Weseixas, I suppose that depends on who to talk to. I had an SL1100, the very first direct-drive machine, and when the SP-10 came out, I wanted one a lot but could not afford it.Maybe three years later (1982??) a friend of mine bought an SP-10 and... | |
| Surface Noise - another question One thing that has not been mentioned here is the role the phono preamp plays in surface noise.Many phono sections use loop negative feedback to execute the RIAA curve and control distortion. These preamps will be found to play surface noise to a ... | |
| How close to the real thing? Maybe y'all will be interested in this- it seems relevant to the thread...Recently I was in the recording studio, we were trying to make a recording of my band. Our bass player is leaving town for a while, and we didn't want to forget some new mat... | |
| vintage turntables? Weseixas, I would agree that *most* Technics machines are rather ordinary. The SP-10s are an exception. They have a lot of excellent engineering that went into their servo design, of the likes that you don't see these days. As a result, they repre... | |
| Debuzzing a Wheaton TriPlanar problem Why not give Tri of Triplanar a call 612-623-0922? I'm sure he can help you out. I have heard that he's not so good at the email (by his own admission). | |
| I've got a mcintosh mx110 that's been sitting ... If this is an original MX 110 and the filter capacitors in the power supply have not been replaced, I would be careful running the preamp- startup on a variac and take and hour to bring it to full voltage- but I would regard its use as very tempor... | |
| vintage turntables? Musicgioni, it kinda depends on the Technics doesn't it? This seems to be at the crux of what you were saying. The 1200 is an OK machine, nothing special. If you want to hear a better one, you need an SP-10 MkII or MkIII. The 1200 is easy to find,... | |
| I am openning a shop. What equipment should I sell The fact that Jim is still here, coming from an economy that was booming, to one that went totally bust, says that he is doing something right.5 years on- 90% of all businesses fail in that time- this is not luck. Congratulations! | |
| How to shop for speakers? Hi Tim, I think you have that backwards: sensitivity is 2.83 Volts/1 meter, efficiency is 1 watt/1 meter. | |
| Damping Factor and Overall Negative Feedback. That results in what is called transient intermodulation distortion (TIM), and enhancement of particularly objectionable odd-order distortion components.It is this last bit wherein you see so much variance in amplifier design: odd orders as stated... | |
| How to shop for speakers? Al makes good points; all I want to do here is emphasize something that he mentions about speaker sensitivity:Sensitivity and efficiency are different measurements! Sensitivity is 2.83 volts at 1 meter, efficiency is 1 watt at 1 meter. Now if you ... |
