| Best Budget Phono Cartridge? Most of the stuff that you read on the net is total crap - particularly the stuff that I write. But there are lots of threads about the eee and I don’t see any that have issues with body ageing (though I have this problem with my body), a recent o... | |
| Best Budget Phono Cartridge? From the looks of it a medium to low mass arm. I would suggest a Nagaoka 110 as a fantastic cartridge. Another approach, since the 681 is such a fine performer, is to get a new stylus for it from JICO. Would suggest that, since you are unable to a... | |
| Nuvista Tubes - General This is old stuff gd. As far as production quantities go, you take what you can get. So if you want to make 300 preamps you need to find the appropriate amount of tubes. As George pointed out, they get their tubes at military surplus auctions. You... | |
| Nuvista Tubes - General George, thank so much. That's exactly it, the pictured tubes in your link are trivistors not Nuvistors. I was sure that you would have the answer.Interesting bit of info as well that MF went to the trivistor when the Nuvistors dried up. | |
| Nuvista Tubes - General George, I didn’t know that fact apparently.Can you give me some insight into the glass cased Nuvistors in your link regarding my question above? | |
| Nuvista Tubes - General George, we will agree to disagree on cap coupling. I don’t see how taking a circuit that is optimized for direct coupling and hanging a cap on it is a test of anything.I do listen to a friends Krell Monos and have owned Krell amps in the past, so ... | |
| Nuvista Tubes - General George, completely agree that the Acro is not direct coupled, and I use the common parlance here, in tube design speak that the output transformer is not included; a direct coupled tube design generally referring to the circuit being direct couple... | |
| Nuvista Tubes - General Wow, what a great question, and one that I can’t answer. I don’t really think that there is a vacuum tube sound, per se. Some tube circuits can sound very linear, and if blindfolded, you might say that they are very good solid-state. And others ha... | |
| Nuvista Tubes - General You are most welcome. To clarify one other thing, Nuvistors are vacuum tubes. They just come in a smaller package than the glass tubes that we see in most gear, and relied on “modern” manufacturing techniques to miniaturize them ( “modern” circa 1... | |
| Nuvista Tubes - General If you like the MF sonic signature, there is no reason not to migrate to the Nuvistor products. Nuvistors are very long lived and quite reliable when used in a conservative circuit. Me, I find the MF products way to soft sounding for my taste. YMM... | |
| Nuvista Tubes - General Of course there are direct coupled tube amps. The Loftin-White instrumentation amps, designed in 1929, and still used today, were direct coupled designs. The Acrosound Stereo 20-20, designed by the brilliant Ed Laurent, only has an input coupling ... | |
| Nuvista Tubes - General Nuvistors were the last vacuum tubes designed and are both highly linear and compact. In addition to Musical Fidelity, Conrad-johnson used them in a head amp, much earlier. They are also found in the FM front ends of late stereo tube tuners, and t... | |
| Best Budget Phono Cartridge? How can anyone make a recommendation without knowing the mass of the tonearm in question? Or was the model of turntable mentioned and I just missed it? | |
| EL34 equivalent tube types Some folks like 6L6 variants as a sub for EL34s. The Dyna ST70 manual actually says to use these in a pinch. So 7581/KT66/6L6 would all work. They are certainly not electrical equivalents of the EL 34 family, and should not be considered direct su... | |
| EL34 equivalent tube types Joe, here here, the Shuggie is a fantastic tube, and one of the very best values out there. Super call.I still have a quad of the welded plate EH 6CA7s and while I am not partial to them, I can see how some will go crazy over them. A beam power tu... |
