| Micro Seiki DD30 Turntable "It works fine until it gets toward the end of the record, at which point it will start skipping and the arm will not advance anymore."Sounds like an open and shut case of something is restricting the travel of the tonearm at the inner grooves. ... | |
| TUBE BIAS, socket to me! In my long experience, tube amplifiers that require periodic bias adjustment typically provide both external test points (female jacks where you stick the pos and neg meter probes) and externally accessible potentiometers with which to do the bias... | |
| Strange thing happened ... Metal fatigue. | |
| Phono pre amp So vdH is making the calculation for you in recommending a tonearm with 14g effective mass. That should not be taken as a firm directive. 12 to 16g would be fine. Note that effective mass should include the weight of the headshell, the cartridg... | |
| Phono pre amp chasda, I won't contradict any of the above posts, but in my experience vdH cartridges come in wood boxes. Inside the box, on the underside of the removable cover, you will usually find hand-written specs for that particular cartridge. Those dat... | |
| TUBE BIAS, socket to me! You may have learned A theory of relativity, but it has nothing to do with Einstein's Theory. | |
| What is the Silliest Accessory You Have Ever Seen. This is a dangerous game to play. One man's meat is another man's poison, and all that jazz. There are lots of add on gadgets being sold to audiophiles that have no discernible scientific justification, but inevitably there will be some who swea... | |
| TUBE BIAS, socket to me! Yes, OK. | |
| TUBE BIAS, socket to me! Elliot, I see no reason why you should be surprised that there are no products currently for sale that mimic your Macintosh MX 110, with an FM tuner built into a preamplifier essentially. FM radio is on the rocks. Not many audiophiles even try lis... | |
| Pure tube phono preamp I am glad Atma-sphere spoke up about his MP1 and MP3. I am a happy owner of an MP1 for about 25 years.up the thread, someone asked about the mating of a SUT to a current drive phono stage. That can’t be done. It’s almost an oxymoron. SUTs step up ... | |
| TUBE BIAS, socket to me! Sokogear, It's a personal decision based on your own listening to music. One cannot say for sure exactly which tube amplifier you might prefer to your Plinius SS one. There are many types of tube amplifier, just as there are a few different stand... | |
| 16 ohm speakers: any amp sounds better with more resolution. speaker cables less critical. Ralph, I am not sure what you are saying, because the terms "multimeter" and "DVM" are so often conflated with one another. VTVM is a clear acronym, because you are talking about a vacuum tube voltmeter. But let's take my Fluke 87 meter. It is ... | |
| 16 ohm speakers: any amp sounds better with more resolution. speaker cables less critical. 0.4V = 400mV, not 40mVAnd 0.4V doesn’t make sense as a bias voltage for an amplifier output tube. It’s way too little. Also grid bias should read out as a negative voltage with respect to ground or with respect to cathode voltage. | |
| Need a sut for Hana ml Mulveling, Although it's a fine distinction, his phono stage should add 62db of gain, not 60db, with a 1:10 SUT into the (42db) MM section OR direct into the (62db) MC section, either way. The resulting output would be fed to a linestage before g... | |
| What about Uni Din? Mijo, You assume that at the outermost grooves the increased stylus velocity compensates for tracking angle error. That is actually an interesting question. I am not so sure one can assume that your assumption is correct. They are two different ph... |
