| Is a SUT needed? Dear Raul, I submit that it's impossible to know for sure that your phono is within .012 db of perfect RIAA, because there's no way to measure that accurately. I'm sure it's as perfect as you can make it, however. | |
| Audio Craft AC-4400 and related AC tonearms Thanks, invictus. I never appreciated the obvious similarity between the graham design and audiocraft tonearms. Seems the latter are quite advanced. | |
| Is a SUT needed? Good points. I would only take issue with the implication that using ICs between an outboard SUT and a suitable MM stage is no different, in terms only of the potential effect of the connecting wires, than having a built-in SUT or a voltage gain ... | |
| Vintage DD turntables. Are we living dangerously? By the way also, unless one has owned the DD from new, one cannot be certain that the electrolytics in the circuit were not already replaced by a previous owner, thus making it seem as if the turntable is defying laws of nature. That's one more re... | |
| Vintage DD turntables. Are we living dangerously? Ok, boys.i really couldn't care less what anyone else does. My advice is sincerely offered, and that's all it is... advice. A more conservative approach with which I would also agree is to inspect all the existing electrolytics for swelling or lea... | |
| Vintage DD turntables. Are we living dangerously? No apology needed.i advise you to replace all electrolytic capacitors now, before any problems associated with their failure occurs. It's cheap to do even if you have to pay someone else to do it. That plus maybe a relube of the bearing should get... | |
| Vintage DD turntables. Are we living dangerously? Your Sony is probably still working because it has had one owner since new, who used it regularly, which is good for the longevity of the electrolytic capacitors inside. But they won't last forever.i hope your glee to read of other people's proble... | |
| Anyone replace the power cord on 1200G? Why do this? Why would it be especially important for a DD turntable? TT's are most often guilty of putting noise back into the AC supply for the rest of the system, so it would be prudent to isolate the AC supply to the TT. Likewise, shielding m... | |
| TT mats bdp24, That's the crux of the matter, when it comes to platter mats, the transmission, or lack thereof, of energy between the LP and the platter. Do you want that or don't you want that? Each of us has to answer that question "by ear". If you wa... | |
| Valves. Brimar Mazda ECC83 grey ladders plates NOS 1962-1972 There is very little tech info on the net about the Lua, but it does seem to be a very unusual piece, apparently using tubes for some functions other than as an output buffer, where the 12AX7 would not be a good choice. Probably the 12AT7s serve ... | |
| TT mats I'd favor Delrin over acrylic, for no good reason. Just a "feeling" combined with the fact that I am not a fan of acrylic platters to begin with. | |
| TT mats Chakster, With reference to my earlier post about EMI, one reason you may like the copper mat on the SP10 is its capacity to block EMI. On my L07D, I am about to compare the OEM stainless steel "platter sheet" (Kenwood's name for the ~5 lb stainl... | |
| Valves. Brimar Mazda ECC83 grey ladders plates NOS 1962-1972 Sorry to divert from your specific question, but I am trying to imagine where you would use a 12AX7/ECC83 in a CD player. Typically, CDPs that use tubes, use them in a capacity that would not be well suited to an ECC83. Are you trying to replace ... | |
| TO BE OR NOT TO BE the user of a record clamp I used to be a confirmed nonbeliever in weights OR clamps. Then I tried my SOTA reflex clamp on one of my turntables (I don't even remember which one), and I heard a big improvement. I also have the OEM record weight that was supplied with my Ke... | |
| technics 1200g tonearm question headshell angled not parallel to lp Invictus, Sorry for misunderstanding the intent of your post. I agree with you that the OP seems to have left the building. In cases where the headshell and arm wand are mis-mated, I HAVE seen some "wiggle", even after the collar is as tight as ... |
