| 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. | |
| Lifespan of a quality solid state amplifier? Herman, that is the correct use of 'half life' in this case. This is what they teach you in technical school. I have seen it borne out many times in the last 40 years. | |
| Lifespan of a quality solid state amplifier? Filter capacitors have a half life of about 20 years. What that means is that in a 20 year period, about half of the caps will have failed. This is true of transistor and tube amps.Sometimes when the cap fails the ESR goes up like Kijanki was talk... | |
| Reel to reel repair - is it worth it? This machine is certainly worth fixing even if you have to pay $250.00. Once you find out what good tapes sound like $250 will seem really cheap. | |
| Building balanced interconnects--ideas FWIW, the whole idea behind balanced line cables was/is to make it so that the cable does not have an artifact- regardless of the cost of the cable.To accomplish this there is actually a standard that has been in place for the last 60 years or so.... | |
| amp for VMPS - RM/X VMPS is tube friendly- we used our amps with them at CES the last couple of years. So you have a lot of options. | |
| surface noise and cartridge/ phono pre questions Kevvwill, I have to admit I was quite surprised when I heard how dramatic this phenomena can be.Turns out that it has to do with the propagation delay (the length of time it takes the signal to propagate from input to output, something that all au... | |
| Problem with my Atma-Sphere M60 It takes about 30 seconds to check for a tube that is arcing. Just knock on the top of the tube. That's the time-honored tradition since there have been power tubes. | |
| Which power amplifier match audio research ref 3 Whatever you go with, to get the most out of your preamp you will want an amplifier with a higher input impedance- 100K or so. | |
| surface noise and cartridge/ phono pre questions Kevvwill, all I can say is that you have to try it to know. Its true that a tick or pop is part of the LP experience, but it is also true that electronics can ring at high frequencies due to stability issues in the design. This will exacerbate the... | |
| Sonic atributes ultralinear vs tetrode vs pentode The document also has comments about OTLs that I don't agree with, as it comes from the 1950s. But the UL stuff it has in it, while obviously biased (if you will pardon the pun) is representative of the general technical/engineering understanding ... | |
| surface noise and cartridge/ phono pre questions Doug is correct- the design of the phono section can influence ticks and pops and this has nothing to do with bandwidth.I can take it a step further- if the phono section uses loop feedback for the RIAA curve, it will enhance ticks and pops. If th... |
