| Does anyone know where I can get transistors for a 30 yr old Spectral amp DMA200? You or your friend might first investigate the possibilities offered here, and then come back if the parts cannot be found. Someone like Nelson Pass or Bill Thalmann may also be able to advise about a modern part that is interchangeable with the ... | |
| Is the DAC the digital equivalent of a cartridge. mahgister, That's an interesting thought if the question was not what the question is. For the question that is, the thought is irrelevant. | |
| Does anyone know where I can get transistors for a 30 yr old Spectral amp DMA200? First, google those part numbers. You might find the parts right away. Then check Jameson Electronics on the West coast. Then ask the Spectral designer if he’s still alive or anyone associated with the company. Then ask Nelson Pass. I hope you’ve ... | |
| Is the DAC the digital equivalent of a cartridge. This thread is based on a “straw man” proposition, and therefore is of value to those who like a good pointless argument. Period. Not that there’s anything wrong with that. | |
| Is the DAC the digital equivalent of a cartridge. Both are transducers. So yes, and….? | |
| Glanz moving magnet cartridges Thanks for the in depth explanation. What I fear is that the suspension has gone bad, but then I wonder why the same would have happened on two samples. Certainly that’s not impossible. I’ll see what I can find for a reasonable cost. Given the mys... | |
| Cartridge incompatibility, Soundsmith and Luxman Obviously you know nothing about quality resistors. Vishay is a big company, and they make dozens of different types of resistors, much like Caddock. So not all Vishay resistors are created equal. One might debate the need for or an expensive nude... | |
| Cartridge incompatibility, Soundsmith and Luxman Tomic, your point, other than the notion about personal preference, is lost on me. Can you be more explicit? Do you really not know what comes after the load R? I’m guessing that was rhetorical. | |
| Glanz moving magnet cartridges Thanks, Dover, and thanks, dgob, for your suggestions. I hadn’t expanded my horizons in the search for a repair much beyond the continental USA. Maybe I should do so. Dover I confess I don’t understand your suggestion regarding a donor. I do have ... | |
| Decided to try a SPU cartridge A SUT converts voltage into more voltage (Jason), at the expense of current, which is only one reason it would be nonsensical to drive a current driven MC section from a SUT. | |
| Cartridge incompatibility, Soundsmith and Luxman The finest Vishay nude resistor costs more like $13. Caddock TF030 costs about $7 each and is nearly as good, maybe indistinguishable. For phono loading, quality counts but the watt requirement is tiny. The change in load resistance is compatible ... | |
| Cartridge incompatibility, Soundsmith and Luxman If the OP wants to sell his Zephyr cartridge, I am interested. Just saying. I don’t advise it, but I’m interested. | |
| Cartridge incompatibility, Soundsmith and Luxman That's for sure. If he wants to let the tail (the 100 ohm resistors) wag the dog, then he must acquire a LOMC with typical LOMC inductance. But also gain must be high enough to work well with the inherent gain of the MC section (plus the linestag... | |
| Cartridge incompatibility, Soundsmith and Luxman Larry, The low output Zephyr already has a low internal DCR of 10 ohms. That's not the problem. The problem is its inductance, which, at 2.5mH, is about mid way between a typical LOMC (about 50 microhenries) and a typical MM (500 millihenries, o... | |
| Cartridge incompatibility, Soundsmith and Luxman Larry, If you read the responses, you will know that the problem is almost certainly the fact that the fixed value of the load resistance at the phono inputs of the Luxman is 100 ohms. The Zephyr is a rare low output MI type, which has high induc... |
