| KLAudio is stopping production of their Ultrasonic record cleaner. I watched that video, and Mr Kirmuss seems very convinced of the merits of his product. But I wondered about what is really generating that white schmutz that then has to be removed by multiple repeat cleanings. It seemed to me it might be a pre... | |
| Has anyone here restored a Sony TTS 8000 platter or a similar strobed platter Perhaps Lohanimal is doing a restoration for his own pleasure and satisfaction. Perhaps he is not thinking about re-sale value. After all, he did not ask for an appraisal. Apparently also (and here Lohanimal can correct me) his TTS8000 works fin... | |
| Replacing components, Please weigh in! Creeds, First of all, I don’t necessarily concede that DC on the AC line causes hum. But I am open-minded to any evidence you can provide. Second, your original post on the subject caused me to do a net search, and the sources I found claimed th... | |
| KLAudio is stopping production of their Ultrasonic record cleaner. I like MF but when has he ever favored a less expensive product over a more expensive one? He will admit that performance is very good but never “better”. | |
| Replacing components, Please weigh in! I did a very quick websearch. Apparently there are products on the market that can block DC on the AC line. One was made by PS Audio and is now discontinued, the "Humbuster III". One other is still made by Emotiva. I suppose that one transform... | |
| Replacing components, Please weigh in! cleeds, I was not aware that DC on the AC power line could cause a transformer to hum. What would be the mechanism of that, I wonder? In any case, even if DC is the cause, the end result is a hum caused by mechanical vibration of the transformer... | |
| Replacing components, Please weigh in! If the hum is coming from the unit itself and not over the speakers, then it probably has nothing to do with grounding. In fact, it is not electrical in nature. It most likely comes from a power transformer directly. Power transformers can vibrat... | |
| Mono Reissues and the Conical Stylus Dave, You wrote, "My take is that if the coils remain oriented at a 45º angle to the record and then wired in series for mono then it is a stereo cartridge wired for mono and it doesn't matter if it if done internally or externally. If however... | |
| LP12- Power Supply- Need education No problemo.if the new SOTA Eclipse motor is DC, and unless Carlin has totally changed his original design, I would bet the control is done on the incoming AC before it’s converted to DC to drive the motor. | |
| LP12- Power Supply- Need education Dear Bdp, I’d like to hear from Bill Carlin himself, if he really said what you say he said. If Bill did say that, of course I would yield to his far superior level of knowledge, compared to mine. But to take your point, first of all, DC is Direct... | |
| Mono Reissues and the Conical Stylus Hi Dave, Do you have any thoughts on the putative benefits of a "true mono" cartridge vs a mono cartridge created from a stereo cartridge by bridging the two channels internally?I think someone originally must have used the upper case "U" to symbo... | |
| LP12- Power Supply- Need education Mijo, With due respect, I think the old problem with the SOTA Sapphire was that the motor was mounted on a stationary platform while the platter, of course, was suspended. When the suspension was activated, that caused the belt to stretch and con... | |
| Loricraft Garrard 301 to Dobbins Sp10 Mk3 - What can I expect ? There are families of DD turntables, just as there are families of belt-drive and idler-drive types. You auditioned only one "brand": Technics. First of all, I find it hard to believe that you didn't hear substantial differences between the 1200... | |
| Loricraft Garrard 301 to Dobbins Sp10 Mk3 - What can I expect ? You might want to audition a Kenwood L07D, before you conclude you don’t like DD. Like other turntable drive systems, not all DD turntables exhibit the same SQ coloration, or lack thereof. Because you’re really saying here that you prefer a certai... | |
| Can you run the HANA SL MC at 100 ohms? Chili, I think you are underestimating the technical expertise of the designer at DB Systems. The kits are meant to be used in conjunction with a phono stage that has a fixed input resistance of 47K ohms. For other fixed input resistances, I sup... |
