| why balanced power last before component? Here are the NEC requirements. You're not running balanced power everywhere, just the audio system, right? At any rate you might want to read all the way through:NEC 647, which defines the requirements for balanced power systems, places some impor... | |
| phase control on BAT VK pre amps You will only hear the effect of inverting the phase if you have a recording with only 2-3 mics in true stereo. 50% of recordings are out of phase anyway, so this can get really tricky. | |
| "Buzz" Coming Through Speakers The first thing to do is verify that the preamp is indeed the culprit. To this end:run the amp with no input- no interconnect cables attached. Is the buzz still there? If yes- its the amp, if no:Reconnect the preamp. Do not have any other componen... | |
| Is a high priced Line Conditioner needed A good power condition can really be a marvelous improvement.Most of them I have seen in high end audio do more harm than good, unless they are operated well below 50% of their ratings. This is especially true if you have a high power tube amplifi... | |
| why balanced power last before component? I've always been curious about the idea of balanced power. Funny thing is though, the balanced transformer systems I have seen use a center tap which goes to ground.Its very well known that this will degrade its noise performance. If there is nois... | |
| Failing resistors in mid 70's Sansui gear Those look like carbon film resistors in the photo. If carbon films or carbon composition resistor get heat during normal operation, they will slowly decrease in value. For this reason they have to be run at values substantially less than their ra... | |
| High End Audio-Gaining Higher Ground? We just mastered an LP for a local band and I don't think anyone in the band was over 25. They wanted to hear the test pressing on our system and while their recording was not particularly impressive recording-wise, they were stunned by the increa... | |
| That "tube sound" and power ratings That's definitely true that in the studio it's processing the signal - but at home, tube amps are often doing the same thing. It is a form of distortion. Not all tube based systems distort this way, but I do see lots of listeners using underpowere... | |
| That "tube sound" and power ratings If anything, the move to tube amps in the last 30-40 years has been for the things that tubes do that are difficult or impossible for transistor amps. I don't see audiophiles that are into tubes doing it for any other reason then they want to get ... | |
| That "tube sound" and power ratings ^^ Charles, I think human nature is the culprit: the most powerful human motivator being to look good, the second most powerful not to look bad. You fail both of those if you don't understand the difference between power and voltage if you design ... | |
| That "tube sound" and power ratings We all know there are plenty of 8 ohm speakers. 16 ohms is a little harder to find. Some examples:Classic Audio LoudspeakersAudiokinesis (several models)High Emotion Audio (Bella Twin- one of the best monitors I've heard)Quad ESL57 and ESL 63Lowth... | |
| That "tube sound" and power ratings Hazyj, There is something to the idea that smaller amps sound better. In the case of push-pull tube amps, this has almost entirely to do with the output transformer itself. The reason for this is that the more power the output transformer can hand... | |
| That "tube sound" and power ratings Further, the topology of the circuit says a lot about what sort of distortion it will make. For example, a push-pull amplifier with a single-ended input will make primarily 2nd ordered harmonic distortion, but will also have some of the 5th. If th... | |
| combination tube amp and ss preamp? Better get crackin- those tubes aren't going to buy themselves. | |
| Did anybody get horns figured with triodes ? I like a bit of power available, even on horns. I use triodes exclusively and my amps have only one stage of gain. I don't use all the power that my amps have, but since their distortion drops to very low levels (unmeasurable) at normal listening ... |
