| Who needs a MM cartridge type when we have MC? Fleib, Never having heard one of these devices, I share your skepticism. However, Audpulse apparently has heard the 12AX7 version in his or some other person's Marantz 7C, and he's evidently impressed. That's all we've got to go on. Like you, I've... | |
| Who needs a MM cartridge type when we have MC? Audie, My use of the word "illegal" was meant to be taken as humor. Nothing more than that.The device described on the website appears to be electrically identical to a 12AX7 tube (except I did not see a rating for "mu", which parameter best descr... | |
| Vintage DD turntables. Are we living dangerously? The impedance of any ESL is a complex function of many factors, but basically an ESL can be viewed as a giant capacitor. Thus it will tend to have high impedance at low frequencies, and the impedance will tend to fall off at the very highest audio... | |
| Who needs a MM cartridge type when we have MC? Holy cow! That's illegal! Perhaps the reason I could not find it under "12AXT" is the fact that its name is "12AX7-WS". What a clever idea. Has anyone besides Audpulse heard one of these devices? Based on specs, it should not give any more gain th... | |
| Vintage DD turntables. Are we living dangerously? Doron,I have always been curious about Joule OTLs, maybe because it's the only brand of OTL I've never owned or heard. I started with Futterman amplifiers in the 70s, owned many variants of the Futterman circuit, and now for the past 10-15 years h... | |
| Who needs a MM cartridge type when we have MC? Follow-up: A Google search on "12AXT" brings up nada about any such device. I then tried searching on "12AXT tube", then "12AXT transistor", again with no result except a list of references to the "12AX7" vacuum tube that we all know about. Aud, w... | |
| Who needs a MM cartridge type when we have MC? Dear Audie, Is the 12AXT a vacuum tube or a solid state device? (If it has no filament, it MUST be solid state, actually.) If the latter, do you know for a fact that it can be dropped in a 7C to replace the 12AT7s or the 12AX7s? (I forget which tu... | |
| Vintage DD turntables. Are we living dangerously? Fleib, RS-A1 is also surface mount with no fasteners to the TT plinth surface. Thus you can (all too easily) move it back and forth with respect to the spindle, if you want to fiddle with where on the LP surface you will achieve tangency. The savi... | |
| Vintage DD turntables. Are we living dangerously? Fleib, I fear we are still on different pages. I am talking about how to mount an RS-A1. To do so, you aim it at the spindle and let the stylus fall about 21mm short of reaching the spindle. It is my belief that thus you will obtain tangency somew... | |
| Who needs a MM cartridge type when we have MC? Audpulse, So far as I know, the phono stage in the Marantz 7C in completely original form IS MM-ready. There was no such thing as an MC cartridge back in its day. It probably does develop higher than average gain compared to a typical modern MM ph... | |
| Vintage DD turntables. Are we living dangerously? Doron, I agree with the others, it's probably best not to run the motor without the platter installed. It's definitely taboo for nearly all other DD turntables, for sure. However, I faintly remember that Bill Thalmann told me that where the TT101 ... | |
| Vintage DD turntables. Are we living dangerously? Fleib, On 8/29 or thereabouts you wrote, "Lew,You mean 21mm short of the lead-out groove, which would be about 80mm from the spindle?" Then Hi-ho made some further comments to indicate that 76mm is correct. But if you guys will look at the diagram... | |
| Vintage DD turntables. Are we living dangerously? Fleib, another such arm that preceded the Rigid Float is the RS Labs RS-A1. As you say, it uses "under-hang" and thus achieves tangency at one point on the LP surface. Both of these arms are in the realm of the crazy, but I can say that the RS-A1 ... | |
| Vintage DD turntables. Are we living dangerously? Ditto to what Pryso says. Downunder, you might consider finding another "tech". The guy you quote is not very tech-y. As Pryso says, the reason to change out the electrolytics has nothing at all to do with sonics (unless a leaky cap is causing a s... | |
| Who needs a MM cartridge type when we have MC? Pkoegz, Perhaps you have seen my posts several days back where I noted my (current) puzzlement as to how to judge my Grace Ruby cum SS OCL stylus. It had a promising first few hours in my system and then became and remains rather shrill and irrita... |
