| 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 ... | |
| technics 1200g tonearm question headshell angled not parallel to lp Photo?Up til now, I thought you were saying that the headshell does not sit at zero degrees azimuth, which means that when you view the headshell "on end", the flat top surface of the headshell is not parallel to the LP surface. If this is NOT wh... | |
| TT mats "coreless", not "cordless" | |
| Which tubes do I change?? Why do you just assume that changing tubes will ameliorate your problem? For example, first of all, what evidence suggests that the problem lies in your phono stage? Bass boominess could be the result of a mismatch between cartridge compliance a... | |
| TT mats bondmanp, Thanks for that info. I will look into that mat for use on the TT101, which also has a coreless motor. Both the TT101 and the L07D motors are derived from the original Dual cordless motor (as is that of the newer Bergmann DD turntable)... | |
| TT mats enginedr1960, Are you blocking EMI with the ERSA mat? I ask because this is worth doing for some DD turntables. On the L07D website, one is advised to do something about that, even though the L07D has a 5-lb stainless steel "platter sheet", whic... | |
| TT mats dorkwad, In what respect are you agreeing with noromance? Noromance uses an LP as a platter mat, not a bare platter. And really, using a bare platter only means that you are placing the LP on a surface that is native to that particular platter. ... | |
| TT mats I guess I'm a zombie, in that case. To each, his own. The BA mats have lots of fans, not too many detractors. What turntable, tonearm, cartridge? I use the BA Mat2 on my SP10 Mk3 with Reed tonearm and ZYX UNIverse cartridge. I also use a Mat2 ... | |
| TT mats Noromance, What you experience as "energy suck" is what some others might experience as proper dissipation of spurious energy that would otherwise generate resonant frequencies audible in playback. I am not saying that you are "wrong" and the othe... | |
| Record’s physical design properties Not only what tketcham wrote, but also keep in mind that moving the CW also changes tonearm effective mass, which can have an effect on bass response if the resonant frequency is near to being too high in the first place. (The position of the CW ... |
