| Hot off the press...Technics SL 1300G Pindac, is there such a product as a clamp that weighs 1 kg? If so, you’re quite correct that such a clamp places the same burden on the bearing and thrust pad as does a 1kg weight. However, no clamp that I know about weighs much more than 100g. I... | |
| HumminGuru Orbit Vinyl Record Static Remover I bought an electrostatic charge meter in order to determine for real what goes on with these devices. The meter tells me that my 50 year old Zerostat still works fine, if used properly as per instructions. Vinyl accumulates a negative charge. So ... | |
| Ringing from the tweeter What’s a “high gain” slot in an all tube device? The tube supplies any gain, so gain cannot be greater than what the tube can provide. I’m guessing that Actusreus’ preamp was picking up RF and that the tubes per se were not at fault; he probably n... | |
| Feel Silly Asking This Question Alignment Parameters Thanks for making me think about that statement. | |
| Feel Silly Asking This Question Alignment Parameters So I just watched the two videos that bill_k referenced, and I don't perceive any conflict between what Peter says and what I wrote, except for the fact I was technically incorrect to have written that the AS force is constant. Upon further thoug... | |
| Feel Silly Asking This Question Alignment Parameters FWIW, I wasn’t notified of your response. The gist of my response to PL is that yes, AS devices might increase the AS force as the stylus approaches innermost grooves, but no, in general AS devices don’t follow the skating force in magnitude. Or ... | |
| Feel Silly Asking This Question Alignment Parameters bill_k, Can you direct me to Peter Ledermann’s quote as follows: "With all due respect you [referring to me, Lew] stated that "AS is constant in magnitude" which is not true. As Peter Ledermann confirms: "A properly designed anti-skating is non-li... | |
| Hot off the press...Technics SL 1300G The spindle itself is a solid, machine cylinder made of stainless steel usually. How can it possibly hurt the spindle to pull up on it as with a record clamp? On the other hand a record weight undeniably puts added burden on the bearing and thrust... | |
| Rays Tubes In many cases, in phono stages, 12AU7 is used at the output, as a cathode follower. The CF is needed to reduce output impedance, so the stage can drive a linestage or amplifier. The CF adds no voltage gain, so the choice of brand or provenance is ... | |
| Straight tonearms without offset angle In fairness to Pindac, I do not think English is his first language, although he has never said as much. My guess is German. | |
| Anyone ever listened to a vintage Victor Laboratory X1 cartridge Wait a week or two. It’s nothing to be ashamed of, but you had a first rate case of expectation bias. | |
| Audiomods Is A Great Company Of the 7-8 tonearms I own, the Triplanar works best of all with my MC2000 (with the qualification that I have not mounted the MC2000 on the Viv Float, yet). I think the estimated effective mass of the TP alone, which would include its integral he... | |
| Source for resistors for an acoustech/sutherland phono preamp That’s hiss-terical. | |
| Hot off the press...Technics SL 1300G JP Jones found the tiny flaw in a PCB that was causing my Victor TT101 to malfunction, after two other excellent techs could not. I then also bought his recreation of the MN6042 chip, which he installed in my SP10 mk3, even though the OEM chip was... | |
| Source for resistors for an acoustech/sutherland phono preamp Expensive resistors are not going to cure hiss, unless an existing resistor is "broken", in which case any fully functional resistor of the same value and equal or better voltage and wattage rating will also cure the hiss. What I am saying is tha... |
