| How many plays can you get out of a good record? Now we have the relatively low cost technology to make transparent digital copies off vinyl re-play. Someone should do this with some newly acquired high quality LPs, wait 10-20 years, keep track of the use, and then play the vinyl and compare it... | |
| How many plays can you get out of a good record? There are so many subjective judgments and system specific elements to your question that it is impossible to answer with any degree of statistical certainty. The first point is who is making the judgment that the record has deteriorated sonically... | |
| Linn LP 12 Malbor, your second post, which asks a new question, is more incendiary than your OP. Best to stick to your question about limited upgrades to your LP12. Cables seldom fail to make a perceived difference but I agree with ghd; save your money for t... | |
| Cartridge Loading.....Part II Using the ZYX Universe, which has an output of 0.24mV and an internal R of 4 ohms, the gain is as much as you’d want, at the 0db setting. So, if you estimate the current output of the ZYX as 0.24mV/4 ohms or ~60uA (micro-amps), it would seem that ... | |
| Thoughts on the Linn LP12 turntable Pani, I hadn’t heard of the Ginga, so your comment led me to look it up. Its design concept channels Mikro Seiki, if MS had been allowed to evolve for a decade or two. The TTs you like by and large could not be more different from the LP12. | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? Although I don’t recommend tube rolling in order to improve sound quality, in this case it might be worthwhile to change all the tubes in the unit. It could be that one or more tubes is defective, thereby enhancing susceptibility to the noise. Eve... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? I give up. | |
| Added an SUT...not sure I understood this Vinylzone, I think you’re correct about the labeling of the SUT inputs, but in this case the best choice is the 40 ohm inputs despite the fact that 12 ohms ( the internal R of the cartridge) is closer to 3 than to 40. That labeling custom can be v... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? This is not an inherent fault of the 834P. Shorting the unused inputs is a good idea. | |
| Added an SUT...not sure I understood this Please omit “gel reader “ from my last post. I have no idea where that came from. Should read “47K or higher” load resistor. Nearly all MM phono stages use 47K standard. | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? Aluminum foil is fine for identifying the source of radiation but if it works you’ll need a more practical long term solution, like possibly tube shields or other. | |
| Added an SUT...not sure I understood this Raul makes a good point, but if you’re determined to use a SUT then you must use a low gain phono stage (40 to <50db) with a 47K or gel reader load resistor. | |
| Talking about service! I had a problem with a Grace Ruby that was re-tipped by SS with an OCL stylus. It just did not sound right. Peter invited me to return it, found the problem, which was due to an error in their work, fixed it, and had it back to me within a week ... | |
| Added an SUT...not sure I understood this What mulveling said. There is only one correct way to terminate the SUT, with a 47K ohm load (or higher in some rare cases for special reasons) across the secondaries and input to an MM phono stage. With a SUT that has a 1:10 turns ratio (like y... | |
| Cartridge Loading.....Part II Don’t have a formed opinion yet. |
