| Anyone try this way to wire your loudspeakers? Not to take away anything from the enjoyment you're experiencing . . . but I thought I'd point out that the 8-ohm taps have about 6dB more voltage gain than the 4-ohm taps. There's no problem with doing this from the amplifier's standpoint, except... | |
| vintage gear esp. tuners with controls on top Try the Beomaster 6000 (later type 2253) ... it's a cool piece with a varactor analog tuner and digital frequency-counter display, and I think it's a bit narrower than the 1200. | |
| Electronics 101: Use of Negative Feedback; a Q Admittedly, I am not familiar with Atkinson's test involving an IHF speaker load. Care to explain what that test is all about?Start with http://www.stereophile.com/content/audio-research-reference-150-power-amplifier-measurements and then read the... | |
| Electronics 101: Use of Negative Feedback; a Q I believe that Ayre SS amps do not use NF in the circuit design, yet have relatively high DFs, thus suggested low output impedances. I don't know how Ayre achieves these results without NF, but they do. No. They use feedback, even if they say they... | |
| Electronics 101: Use of Negative Feedback; a Q I've taken an interest in the past year or so of trying to understand the exact origins of this idea . . . that is, that Global Negative Feedback is a Bad Thing. I think that there are three opening points here that can be accepted as fact:- The u... | |
| Amplifier Capacitance Speaking to the original poster's question . . . yes, there are side effects to unduly increasing the filter capacitance, even though there are many "high end" amplifiers that are designed without regard to them.Keeping focused on conventional sol... | |
| Is there a service to install CDs in a Server? Larryi, you might give them a call to discuss the specifics of what you're after . . . I know that they've tailored some of the specific tagging conventions to work with particular servers, but WAVs present some unique metadata challanges with any... | |
| Is there a service to install CDs in a Server? I have used Terra-San http://www.terra-san.com to rip many batches of CDs, totalling a few thousand . . . and have always been satisfied. They have no problem with you simply sending all the CDs in their jewel cases, and can even send you the pack... | |
| Will An Attenuator Help Reduce This Hiss? Let's say that full power corresponds to an SPL at the listening position in the vicinity of 110 db. In that situation -115 dbv at the amplifier inputs would result in an SPL at the listening position of -5 db, surely not audible.It's important to... | |
| Will An Attenuator Help Reduce This Hiss? A two-resistor attenuator like the one Al describes seems simple and elegant, but there is another serious side-effect besides the issue of excessively loading the source -- it's the fact that raising the source impedance driving the amplifier wil... | |
| Output watts per tube Despite having 6-800 hours on them, ten of the twelve tested between 100 and 110 on a tube tester, and the other two came out between 85 and 100. This was using the sensitivity set at 53, per that tester's standard for the tube type.this number re... | |
| copper slug I must say I'm quite alarmed how non-chalantly this discussion has turned to materials for bypassing fuses . . . I'm thinking perhaps this may be a Bad Move from a safety standpoint. | |
| Nakamichi CD remote trivia? Could it be that as Nak transitioned from the green lit CDP-2A to the orange lit, simliar spec but different layout, CD-4 that the factory already had the later model remotes available to ship with the CDP-2A?Of course! Most remotes are outsource... | |
| How do we remember 1970s amplifiers? Eldartford brings up an interesting subject in that many of the amplifiers with more humble aspirations in the 1970s were capacitor-coupled . . . Johnnyb53 mentioned that his Altec integrated stereo had issues with reduced power output at 20Hz, wh... | |
| How do we remember 1970s amplifiers? Pubul57, aside from tons of repair and modification, my audio design experience revolves mostly around small-volume or one-off custom stuff for pro audio applications . . . various iterations of analog and mixed-signal "preamp"-type stuff. This ha... |
