| KT88 vs 6550 vs ? for warm midrange - using Cronos Mag lll You need to get hold of the plate curves for the two tube types. That’s a graph displaying plate current vs plate voltage with separate curves for each bias setting displayed on that background. See how they compare.Then make some measurements of ... | |
| Vinyl records & Discwasher cleaner Did it work “great”, or was it just a successful marketing phenomenon at a time when there was no serious competition? | |
| Vinyl records & Discwasher cleaner As I recall, it was odorless, which means it had to be quite dilute, if it contained alcohol. Or that any alcohol had evaporated by the time I took a whiff. | |
| Vinyl records & Discwasher cleaner Among audiophiles I knew back in Diskwasher days, more that a few thought the fluid was just water or very diluted alcohol at best. What’s the inside scoop on that? | |
| Will a record weight harm the motor in a direct drive turntable? Aldo, I own an L07D and the record weight that optionally came with it. I’d guess it weighs 250g, tops. I also use it on a Victor TT101 and on my Lenco which has a massive aftermarket bearing. But the problem is when you get up over 500g or even m... | |
| fozgometer v2 Please correct me if I’m wrong. I’m sure the foz works as advertised to equalize crosstalk. But what I and others have said is that in doing so, the stylus tip in many cases will end up slightly askew with respect to the groove, unless the coils a... | |
| fozgometer v2 Do you really anticipate that you’ll only align one cartridge for the rest of your life? Anyway, in my opinion you don’t need a fozgometer. Just set azimuth so the stylus tip sits symmetrical to the groove walls, which almost always means set azim... | |
| Phono Stage - The great analog tragedy For me, the most consistent difference between home audio and real life is dynamics. The most convincing demonstration of that was having a sax played live in my listening room, with the musician standing between the speakers. Wow! | |
| Vinyl Warm Up Time Solid state devices have an ideal operating temperature, just like tubes. Even if you leave your SS phono stage or preamplifier in "stand by" mode when it is not in use, the audio circuitry still has to warm up a bit after operating DC voltages ar... | |
| Vinyl Warm Up Time Joey, baby, a phono cartridge is most apt to "warm up" before sounding its best, among all other audio gear, IMO. It has suspended moving parts, and the suspension is made from organic materials or synthetic versions thereof. Those materials hav... | |
| Thorens TD124 “Mk1”/Mk2 plinth Larry, I don't claim to know much about resonance control, except by observation and an attempt to apply some logic. Also, I never know if I have achieved the best result possible based on the science. I only go by what I hear. For example, I li... | |
| Thorens TD124 “Mk1”/Mk2 plinth I can believe that cast iron is relatively nonresonant, if only because Albert Porter uses a large cube-shaped cast iron block to dampen the bearing inside his Panzerholz plinths for Technics SP10 mk3s and Mk2s. When I was creating my own plinth f... | |
| Thorens TD124 “Mk1”/Mk2 plinth Schopper call it “bronze”. Which is an alloy of mostly copper and some tin. No iron content. | |
| Thorens TD124 “Mk1”/Mk2 plinth Maybe. But if it’s the resonance of iron , then why would a nonferrous aftermarket subplatter suffice as a substitute where the mk2 nonferrous sub platter is judged to be inferior? | |
