| Turntable Thanks. I guess the problem with low rpm would especially apply to an inverted bearing turntable. I am not sure that the braking effect of the grease bearing in an early Garrard 301 is totally analogous with friction but others refer to that cons... | |
| Turntable Bruce, Thanks for your expert input. You wrote, "Also because TT bearings operate at low rpm bearing "failure" is a possibility and in this scenario reduced friction of the surfaces can be helpful." Why does operation at low rpm's enhance (rath... | |
| Valve phono stage Chakster, It seems you repeated back to me exactly what I said to you; an ECC801 is not likely also to bear the stamp "12AT7WA". Apparently we agree on that, and we agree that REAL ECC801s/802s/803s are very rare and very valuable in the crazy tu... | |
| Valve phono stage I have to wonder about the tubes you mention, specifically the ECC 801/12AT7 WA. Because WA is a suffix that was used I think by Phillips, and Phillips never made any ECC 801’s. At least so far as I know. Your tubes might legitimately be ECC 81s. ... | |
| Valve phono stage Dear Chakster, there’s no reason for you to pay any attention to me, but it does seem that you are missing my point. So now you’ve described the particular tube amplifier that you found to be less good sounding then your 1st W amplifier. That pro... | |
| Valve phono stage Chakster, perhaps your problem is that you have been into an NOS vintage tube equipment and maybe not into the best modern tube equipment. And for sure another problem is that you are conflating phono stages with amplifiers. In my opinion, the out... | |
| How much isopropanol is effective but safe for viny? Invictus, I don’t necessarily agree with your thesis that 98% isopropyl alcohol would not damage a record even after a prolonged exposure to it. But in practice this would never happen in my house anyway. | |
| Phono Preamp Recommendations Chakster, I thought you were going to try a Nelson Pass phono stage next. Because ss is so great. The Xono Phono is generally $1500 to $2k used, but I think his latest designs are much better. | |

| Valve phono stage Raul, The OP ASKED about “valve” phono stages, preferably balanced ones. In case you don’t know, valve means tube. So naturally the discussion has been about tube or valve phono stages. And your gross generalizations only reveal your own obsession. | |
| Valve phono stage bpoletti, I don't think you are qualified to argue "facts" with Ralph. The fact that you don't know when you are over your head is only further proof of that. He's too nice a guy to tell you. | |
| How much isopropanol is effective but safe for viny? Yep, I am sure you do consult the Dick Doctor. I've already asked, what are your "facts"? State your case. My own "arrogance" is based on trying to find the truth, only. If I were to find well conducted science that proves your point, I would b... | |
| How much isopropanol is effective but safe for viny? I found this, from an article written by a chemist:"Unfortunately, there are many misconceptions related to plasticizers – for example, about phthalates “leaching out” and “easily dispersing/gassing out” from PVC products. This is actually unlikel... | |
| How much isopropanol is effective but safe for viny? bpoletti, After a search of the scientific literature to support your claim (which I have heard before this) that alcohol removes plasticizers from LPs and could by that mechanism damage them, I found exactly one reference, which is contained in a... | |
| Turntable So far, Helomech offered the most cogent point. Make sure your turntable does not have sintered bronze bearings, by all means. And then don't use the stuff regardless.Friction in a piston engine, which lives at very high piston velocities and wh... |
