| surface noise and cartridge/ phono pre questions Panu21, it *can* be, but can also be a setup problem with the arm and cartridge. If the cartridge is not loaded properly, and is not set up correctly, it is conceivable that the additional RF energy that shows up at the end of the LP could bother ... | |
| Efficient speakers with high powered ss amp? Rischa, go look at the link I posted earlier. It relates directly to your question. | |
| Lifespan of a quality solid state amplifier? Most electrolytic caps used in power supplies will show some signs of failure before they start to leak. Most such capacitors have some sort of plug on the terminal end that will show signs of bulging prior to outright failure of the part.Its a ju... | |
| surface noise and cartridge/ phono pre questions Jcarr, I think you may find this article by Nelson Pass to be interesting:https://passlabs.com/articles/audio-distortion-and-feedbackIt seems to re-enforce some of your comments above. Norman Crowhurst wrote about some of this as well, although I'... | |
| Efficient speakers with high powered ss amp? You might want to look at this link:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpThe issue of the intention of the designer will play a huge role in this matter. In fact, if the amplifier technology does not match what the... | |
| Why 24/7 warm-up period on amps? Rower30, I do not blame you for taking that position, and no doubt this is why there are a number of 'HiFi' fuse products now available.However you can also consider the fuse to be a common denominator in the AC chain, in that you might use the sa... | |
| Tube question for the electrical engineers If you are using Chinese signal tubes the life may be less than 2000 hours if you are using LOMC and need low noise. They can be very quiet but can go downhill in only 1000 hours.Had you considered a step up transformer for the phono section? You ... | |
| Lifespan of a quality solid state amplifier? I'm with Cathode on this one. | |
| Tube question for the electrical engineers A line disruption should not affect the tubes at all.OTOH, it is normal for signal tubes to start out quiet and slowly built up noise as they age. In the old days there were some tubes that were rated for 10,000 hours but no-one does that today. S... | |
| Balanced XLR to RCA Adapters: Good or Bad? My experience is that adpators are not a good idea- they will rob the system of life and impact. So my vote is to change the connectors on the end of the cable.The advantage of running balanced in the phono is (especially if you run LOMC) that the... | |
| surface noise and cartridge/ phono pre questions Jonathon, I'm guessing that you've not heard one of our preamps in probably 15 years! Time to hear one again :)I agree that its possible to use feedback without surface noise issues, but- its a lot harder to do. In addition, I have found that univ... | |
| Current Delivery for Magnepans IME 100 watts is plenty for the 1.7. Since its a 4 ohm load, that means to make 100 watts the amp has to make 5 amps.That's a far cry from 40 amps... in the case that you mentioned, the 40 amp spec has nothing to do with amplifier power. Instead, ... | |
| Lifespan of a quality solid state amplifier? Hi Herman, I too have taught in technical schools and my stint in the service industry goes back to 1974. That's how I financed my way through the Minnesota Institute of Technology. The use of 'half life' is my own and simply comes out of experien... | |
| Lifespan of a quality solid state amplifier? English is an evolving language. 'Half life' works really well in this case since you have the statistical issues of a single cap and also that of several.In the case of a single cap its half life is 20 years on average. IOW, you will find that it... | |
| Building balanced interconnects--ideas Don't shield the wires separately. You want the twisted pair to have a common shield. |
