| The Arm/Cartridge Matching Myth Even though there's normally no musical content below 20Hz, there is a variety of noise caused by friction, and the mechanical reality of tracking. What's the amplitude peak of undamped low frequency resonance? What exactly is it that's resonating... | |
| Who needs a MM cartridge type when we have MC? Hi Kevin, Sounds like you've done some interesting things, a tube driven fusion reactor? Dan didn't have the phono stage perfected until around '90, the start of an unfortunate decade for vinyl enthusiasts. I was trying to remember what cartridge ... | |
| Who needs a MM cartridge type when we have MC? Lew, These weren't Acoustat amps. Only the transformer and chassis were original. The amps were custom made by Dan Fanny (AHT). I believe 5KV is the polarizing voltage and tube voltage could be higher?The original tubes were some kind of high volt... | |
| Who needs a MM cartridge type when we have MC? Hi 3ox, I think the Acoustat panels can be driven with much lower voltage, but I'm sure the storage caps were banks of 50KV each. Each amp had 4 cap tubes. This was around 30 yrs ago and I didn't design the amp or know/understand exactly how it wa... | |
| Goldmund Studio - still relevant today? Harold,I don't doubt your tale of two tables, but I don't share your experience. Maybe it was learn as you go, but if you put the effort into the Studio as the Delphi, you might be singing a different song. At least that's my experience and I'm no... | |
| Who needs a MM cartridge type when we have MC? Back in the day there were variable resistance MM stage preamps. That TNT article I linked to previously, Load the Magnets, has a picture of the back of a Luxman C12 with a pot for resistance. That article is a good one for understanding how this ... | |
| Goldmund Studio - still relevant today? Is the Studio/T3F still relevant for the used price they command? It depends on your point of view. Is a 301 or a 124 still relevant? Certainly wouldn't buy an original example of one of those expecting it to be plug-n-play. The Studio has the bee... | |
| Who needs a MM cartridge type when we have MC? One load fits all? HO carts require more attention to loading than MCs. Two of the three variables of electrical resonance, the LCR circuit that interacts with mechanical response, is under your control, or it should be. As a general rule vary res... | |
| Grace F9 question It appears as if the bodies all have the same generator.The L and Gold with 5.5mV must have stronger magnets. Those two could be the exceptions. Are the magnets attached to the stylus assembly? For those in need, Soundsmith makes a complete replac... | |
| Grace F9 question Thanks for all the replies. The two models listed with higher output is still a bit of a mystery. Mofimadness, PM sent. Thank you.Regards, | |
| Grace F9 question I heard the original Ruby back in the '80s. Unfortunately, I didn't get one. I was into MCs. I'm trying to determine if the ones listed as having 5.5mV output have the same generator. I have no doubt that an F9 w/Soundsmith rebuild or stylus assem... | |
| Grace F9 question Hi Mofimadness, Thanks for your reply. The database seems to be contradictory and I'm hoping someone has specific knowledge, like original owners manuals - specs.According to the database most of the F9 series has 3.5mV out, 1700 ohms impedance. T... | |
| Who needs a MM cartridge type when we have MC? AP,If you're using the line stage section try substituting 12au7 on the output. If you need more gain on phono maybe the high gain Jet City substitute will do it? You'd have to try it. I have no idea if it's appropriate. http://www.diyaudio.com/fo... | |
| Who needs a MM cartridge type when we have MC? Lew, I never herd of them either. Apparently AMT uses matched fets and probably the JetCity as well. I didn't see AMT for sale and I have no idea about any qualitative differences.Seems like they get mixed reviews on musicians sites, mostly positi... | |
| Which tonearm with a Soundsmith The Voice? There is no ideal mass. Those calculators are only an estimate anyway, results may vary. You could buy a mediocre arm and have an "ideal" resonance of 10Hz, and it would be outperformed by a higher quality arm where the resonance is outside of the... |
