| Speed problems with Pro-Ject Debut III Palasr,Yes, I am aware that it is a synchronous motor. I was trying to account for what the poster said. He is NOT using an outboard power supply for the motor, and I doubt that the built in circuitry regenerates AC and could be outputting the wro... | |
| Koetsu vs Dynavector vs Lyra?? If you like the Koetsu Rosewood sound, another Koetsu would be the safest bet. The Onyx Platinum I've heard, though is not nearly as warm sounding as a Rosewood, so there is a signficant difference within that family.Still, the Titan would be a mu... | |
| Tube testers- I've heard grumbling of a ...... I've owned the Amplitrex for quite some time now. It is a terrific, easy to use, reasonably versatile tester. It can, coupled to a computer, even be used as a curve tracer. I have been told by a friend that this tester tests at full power, unlike ... | |
| Is too much power in an amp really a problem? The sentiment that one can always benefit from more power, may be true, assuming nothing else is lost in attaining more power, is often grounded on demonstrations that live music has an enormous dynamic range. In particular, a piano, and symphonic... | |
| Speed problems with Pro-Ject Debut III The motor is, I believe, a 16v motor. So, it already has, built in, a means to step the 230v down. Just plugging it into a 120v socket would mean that the motor was probably receiving only half the voltage it needed, so it was running slow for tha... | |
| Speed problems with Pro-Ject Debut III Elizabeth is correct, the pulleys have a different diameter. The speed of an AC motor is determined by the frequency of the alternating current, not voltage. The converter only changes the 230v to 120v, but does not change the 50 hz to 60 hz frequ... | |
| 2a3 tubes I have a number of 2a3 tubes, including Sophia Electrics from quite a few years back, Shuguang, JJs, and both Emission Labs meshplates and Emission Labs solid plates. I like the Emission Labs meshplates the most, followed by the solid plates. The ... | |
| Static or line voltage instability Dedicated lines will isolate your system from hash feeding back from other appliances on the line and reduce the voltage drop caused by other appliances drawing on the line. But, if your whole house got a nasty spike, it would not do anything for ... | |
| cart measurement vs quoted spec Axelwahl,Thanks for the further information. I think there is a good possibility that your cartridge is "slightly" defective. The "buzz" on Ortofon is that quality control is not one of their strong points. A misalignment of any of the generating ... | |
| cart measurement vs quoted spec Axelwahl,If the cartridge in question is the Ortofon PW, is this the same cartridge that you praised as the best cartridge you have heard apart from the Transfiguration Orpheus, or is this another iteration? I agree that your measurements are disa... | |
| Kudos to speed controllers Motor control units do substantially improve the sound of tables, though probably NOT because of more accurate long term speed control (what is measured with the strobe). The motor on the Basis table is an AC motor. It's speed is is determined by ... | |
| Influence of stylus shapes on distortion Headsnappin,Often, it is a big factor, particularly with used records. When records are played and damaged by a stylus, that damage tends to be located at a certain depth of groove. Another stylus that rides at a different height may avoid the dam... | |
| the tough question: Which preamplifier? and why I have found that the LEAST predictable interaction is between preamp/linestage and an amplifier. A lot of times, a combination that I think will work well does not do so at all. This is a must experiment situation. Tube preamp/linestages, in part... | |
| Influence of stylus shapes on distortion It might be just the case that, in more recent times, I've become more picky with setup. However, I do have the impression that cartridges with fine line profiles are extremely sensitive to VTA change. I have seen the charts that show that even fa... | |
| SET vs OTL Paul,The pushpull 45 amps were built by a Russian guy named Pavel and were sold through a Washington, D.C. area dealership (Deja Vu Audio). These amps used Acrosound TO-330 output transformers (the feedback taps not employed, obviously). The wirin... |
