| 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... | |
| Hot off the press...Technics SL 1300G Find him at Fidelis Analog. He’s a qualified EE who may even have an affiliation with Technics. Among other things, he re-engineered the MN6042 chip needed to make the first generation Technics TTs run correctly using discrete parts on a PCB no bi... | |
| Hot off the press...Technics SL 1300G And the SP10R platter mates and fits a 1200G? Which surprises me even more than the fact you can acquire one. But I suspect JP would have the wherewithal to make that work, if no one else in the US could do it. | |
| Rays Tubes Carpathian, it’s really not that hard to understand the differences among tubes, if you read some basic texts on the subject. Of course before substituting one type for another you need to understand how to read the data sheets. | |
| Rega Planar 3 upgrades Good, easy to use protractor: Feickert. More complex to use and more expensive: Smartractor | |
| Rays Tubes The carpathian, yes, 12AU7 and 6 or 12v FQ7 are interchangeable, but you have to choose the version of FQ7 that matches the available filament voltage. Same specs for all other parameters, more or less. | |
| Hot off the press...Technics SL 1300G Still wondering how west coast got hold of an SP10R platter. | |
| Hot off the press...Technics SL 1300G How and where do you buy an SP10R platter as a separate item? |
