| Most Musical 6NS7 tube for a Preamp? Yeah @atmasphere, for pre-amp applications, Roger had a hard-on for the 6DJ8 (used in his RM-5 and the Audible Illusions Modulus 2 & 3). He was a man of "firm" opinions. ;-)@bdp24 We used the 6DJ8 in some our early stuff, since the tube is v... | |
| Grado/Rega Hum Yes, I've had several people bring their turntables to us for this problem. The tricky bit was how to attach the wire to the motor; I did it by filing off some of the plating on the motor which exposed enough material that I could solder to. I sim... | |
| Is there such a thing as too much power? So, at least for the 2 manufacturers above, higher power is possible & better :-) It is only the cost that will be the negative aspect.From a designer/manufacturing/engineering point of view I can tell you that this is simply incorrect. Its ... | |
| Hum Problem with Grado Another way to eliminate the hum is simply to see to it that the motor has a wire between it an the tonearm ground. | |
| Grado/Rega Hum Changing cartridges is the only sure fire way to eliminate the hum.This statement is false.All that is needed is to ground the Rega motor to the tonearm ground and the problem is solved. The tricky bit is the motor is sealed and not easy to solder... | |
| HELP! - Need a Repair Recommendation for my Raysonic Amp I put a fresh fuse in and it doesn't blow when I push the power button on. Nothing at all happens. Pulled fuse and checked again. Still good.Was it plugged in properly (did it light up)? If it lit up but nothing happened, in my estimation the... | |
| Is there such a thing as too much power? The reason the industry moved away from high efficiency has a lot to do with the large size of typical high efficiency speakers. Not all higher efficiency speakers are all that large. Many 'full range' drivers can be quite efficient yet the cabin... | |
| seeking recommendations for a preamp How does one diagnose a standing wave ?@adrianleewelch If there is bass in other places in the room or the house but not at the listening chair then you have a standing wave causing cancellation at the listening chair. | |
| Most Musical 6NS7 tube for a Preamp? @bdp24 Roger and I disagreed about his assessment of the 6SN7. For some reason he only used the early Tung-Sol documentation to support his views of the tube as you can see in the YT video. The issue was corrected by Tung Sol in later versions an... | |
| built-in phono stages -- good idea? Wouldn't the shield box easily shield from the motor?It depends on the material. I've found over the years that ferro-magnetic materials in the chassis can affect the sound of the product. Especially when using a single-ended circuit though, placi... | |
| Direct Drive vs. Idler Drive vs. Belt drive Right Atmasphere, if on a "proper stand" which includes the floor and everything under it, a situation most of us have no control over. On any wood joist floor you will be in trouble. Those of us on concrete slabs are lucky. I personally do not th... | |
| HELP! - Need a Repair Recommendation for my Raysonic Amp It seems unlikely that the power transformer has failed- a rectifier is far more likely. .Power transformers have to be dipped in something very much like varnish to help them have low mechanical noise. Then they are baked- so you can get bubbles.... | |
| Most Musical 6NS7 tube for a Preamp? The 6SN7 is in my opinion the best tube for a line section in a preamp. Back when we started using them the tube was considered obsolete and no-one used them at all. Obviously that’s changed in the last 30 years!The Pass Labs XA25 only has single-... | |

| built-in phono stages -- good idea? This would bring the following benefits to its performance:Elimination of the sensitive and susceptible phono cableReduction of the need for a balanced phono stage Reduction of noise without the need for balanced design -- half of the battle is wo... |
