| Vintage DD turntables. Are we living dangerously? Henry and Don, From Henry's first post about the pigskin mat, I got the idea he was saying it was supplied OEM with the TT101, perhaps not with the TT81. My TT101 has what I deem to be its OEM mat, but it sure does not look to be made of any natur... | |
| Tonearm: Well Tempered Lab LTD MK2 Raymonda, It's a pivoted tonearm, right? If it has no bearing, then what does it pivot on? The answer is, it does have a bearing. That "paddle or ball in silicon fluid" constitutes a bearing, for better or worse. Don't be concerned; I am not confu... | |
| Vintage DD turntables. Are we living dangerously? CT, The nice thing is, my Alfa does not have to be so reliable, as I will not be relying on it except for the occasional spin on local roads. But I do expect it will be more reliable than the TT101 has been so far. FWIW, I owned a Duetto for six y... | |
| Vintage DD turntables. Are we living dangerously? Four days and the TT101 is still running reliably in the nude, back in its QL10 plinth. I realize no one gives a damn but me, but I just thought Halco would appreciate my keeping his thread alive.I am convinced that the bottom canister cover, now ... | |
| Cartridge impedance loading question John, I won't make a "religion" out of it, if you won't say I was making a religion out of it. The hostility in your response is inappropriate. I only relayed my preliminary and to me surprising observations; I did not say anywhere that I had foun... | |
| Tonearm: Well Tempered Lab LTD MK2 I wouldn't blame a tonearm for "hum and noise" necessarily, but I am no fan of WT tonearms, either. Because the ones with which I am familiar have rather vague bearings and do not maintain precise azimuth. But in fairness, I am not familiar with t... | |
| Storing tube gear I don't feel super strong about this, either way, but on balance I would leave the tubes installed, because the contact surfaces of empty tube sockets can oxidize or collect dirt from the air, otherwise. Definitely the most important thing is to b... | |
| Vintage DD turntables. Are we living dangerously? Today its freezing and raining and gray outside. I took the opportunity to re-mount the now nude TT101 back into its heavily re-enforced plinth. Lo and behold, it still works. I am keeping my fingers crossed. | |
| Cartridge impedance loading question And a cool cat, too. | |
| Cartridge impedance loading question Pkoegz, When you mess around with very low output cartridges, there are many sources of noise besides RFI. If you hear noise, a careful investigation is in order to try to reduce it or eliminate it, but in some cases, especially with an all-tube p... | |
| Skeletal vs Plinth style turntables Ct, For what it's worth, I built two plinths of the type you describe. Both from slate slabs, and I was motivated not only by the principle that there should be a rigid association between tonearm pivot and bearing/platter but also by the simplici... | |
| Cartridge impedance loading question John, Please see my post above and Atmasphere's post above that. The numbers say that what you say is happening in the audible band is happening at way way higher frequencies than that. Can you offer the math? Aside from that argument, if you list... | |
| Cartridge impedance loading question Interesting: The URL offered by Atmasphere gives access to calculators for both RC and RL type filters. Using the RC calculator, I cranked in 150pF as an approximation of capacitance of my tonearm wire plus that of the phono input stage (which is ... | |
| Cartridge impedance loading question Atmasphere is of course correct re the ease with which the load R can be changed on the MP1. I, however, never happy unless I am messing around, have installed a 4-pole, DT switch on the rear panel, such that I can choose among 3 load resistances ... | |
| Cartridge impedance loading question Don, The phono cables are the OEM cables supplied with the Kenwood L07D and L07J tonearm. These are very low in capacitance Litz type. I re-terminated them with male XLRs, for use with the Atma MP1. |
