| Victor TT 801 So my original hunch that the 801 could be a 101 that uses more ICs and fewer transistors now looks to have been correct . But chakster was so certain the electronics were from the 81....Replacing the electrolytics in the PS should not necessitate... | |
| How good is the Micro Seiki DDX-1000 Direct Drive turntable ? 950 for sale on audio asylum. $8000 with phono built in and tonearm. Looks very fine. Floor-standing, so shipping from Singapore might be problematic. | |
| Herron VTSP-2a vs EAR 324 It doesn't have to be all tubes vs all SS. There are several hybrid designs that use discrete transistors in conjunction with tubes to achieve high gain with low noise. Manley makes two such phono stages, but there are more. | |
| 2020 update : JC Verdier La Platine Ct, Your remark, to follow, makes no sense. "If Chakster provides the answer to us, he will have also explained to Lewm why his post based on theory, does not work. "If you want to say that despite its flaws you dearly love your Verdier, that's gr... | |
| Advise on Long Phono Cable run Just to kick a dead horse even further down the road, you could choose a moving magnet cartridge that requires a high-capacitance load. For example some types are flattest in response when they have as much as 400 pF or even more of capacitance o... | |
| Repair Vintage Bang &Olufsen ? Which is why I don’t advise driving to SS for at least a month. | |
| Advise on Long Phono Cable run “Pro sound operators” are dealing with line level signal voltages ( 1-2V). Here we are talking about 5-10mV at most, even from a high output cartridge. Different ball game. | |
| 2020 update : JC Verdier La Platine In one version of theory, the motor pulley should be as close as possible to the platter so as to minimize (but not eliminate) belt creep. Belt creep occurs because the tension on the belt (string or other) is always greater on the "pulling" side... | |
| Advise on Long Phono Cable run Chakster made a good point. I recommended an MM cartridge, but as he notes, MM cartridges are capacitance sensitive. More so than either MI or MC types. So I agree with his recommendation for an high output MI type cartridge. Second, it goes witho... | |
| Direct Drive vs. Idler Drive vs. Belt drive cleeds, I took examples of 1kg vs 5kg out of thin air. Most OEM platter mats weigh less than 1kg (2.2 lbs). I picked 5kg as the upper extreme, just because it is 5 times what might be the weight of a heavy OEM mat. Furthermore, a lot of the vintag... | |
| Advise on Long Phono Cable run If you MUST do this, find the absolute lowest capacitance cable (per foot) that exists, use a high output cartridge (MM or MI recommended over HOMC), and expect to have to live with some sonic degradation. If you live in a high RFI area, expect t... | |
| What was wrong with the P-mount ? chak, This or that will work for some P-mounts, but aren't the Technics P-mounts "special", like B&O P-mounts? Be sure of compatibility. | |
| Direct Drive vs. Idler Drive vs. Belt drive With any DD that uses any sort of servo feedback to maintain constant speed, the feedback circuit was designed for a particular platter mass. If you change the platter mass dramatically, it is quite likely you will do bad things for speed constan... | |
| Recently Inherited a Kenwood L-O7D I wonder how Dolphin7 is doing with his L07D. | |
| What was wrong with the P-mount ? The P-mount was adopted most notably by B&O back when they made some of the best sounding MI cartridges, ever, in my opinion. Peter Ledermann must think highly of them too, since he has devoted his company to repairing the old MMC series and b... |
