| How hot is too hot? I would seriously question the integrity of the amplifier if the case temperature was so hot you can't hold your hand on it. If the temp is that hot, the varnish type insulation in the transformer core will degrade. If your bias current is off by ... | |
| Power Measure? There is an easy fix here. If you are only interested in voltage sags, which is the biggest problem, then you can buy sn inexpensive digital voltmeter with a max/min function. Set up the voltmeter for AC Volts, connect it to the power amp line cor... | |
| Surge protection, no filtering, no regen please... Frankly, you probably won't be able to buy anything that will protect you from lightning. There is do much energy in one bolt that there isn't much you can do about it. Look at it this way, the average lightning bolt has enough energy to lift the ... | |
| Let's build a subwoofer interconnect Funny thing, I just went through this same excercise. I opted for Blue jeans cables and I used the subwoofer interconnect they recommend. After doing the math, I came to the same conclusion they did.I do agree with the comment above about the subw... | |
| High priced power cable what about the romex Punkuk: Pick up a 12 gauge or 14 gauge IEC power cord at your local electronics shop for around 10 to 15 bucks. It has 3 to 4 times the conductivity of regular power cords.The problem with RF and EMI is that after you spend a few hundred bucks to ... | |
| long interconnects and short speaker cables Good grief, Charlie Brown, no one answered Mrtennis's question.Do this: Find out your interconnects capacitance rating in pFd per foot. This will be a number around 10 to 250 pFd or so or maybe more if you have high capacitance cables.Multiply thi... | |
| Why do digital cables sound different? Actually, if a digital waveform is distorted to the human eye on a scope, then it is distorted. There are built in test parameters you can put in to determine if the waveform is in spec or out of spec over a period of time.Check out this link:http... | |
| Cartridge alignment help. This is a tracking problem of your needle not following the grooves properly. The last few grooves are have less circumference in the record, so the track velocity is higher. Thus, it is harder to track the inside grooves compared to the outside o... | |
| Dynaco PAS 2, want to upgrade recifier section. You might to a Google search on this. There are tons of mods out there. No sense reinventing the wheel and making all the same mistakes in the process. | |
| where to buy a BNC to RCA component cable? www.bluejeanscables.com They will custom build anything you want with good cable. | |
| Is it Ok for RCA barells l&r touch each other Actually, unless your system is totally dual mono, complete with separate volume controls in separate chassis, then the grounds are tied together. Even in a complete dual mono system, I would be surprised not to see them tied somewhere together.It... | |
| how can a line cord affect frequency response ? Dpak996: Triggering on both, but not at the same time! For the line cord waveforms, I'll trigger on the line. For waveforms on the filter, I'll have to trigger on the ripple, as the music signal will, or at least should, be very small in compariso... | |
| how can a line cord affect frequency response ? Metro04: I was basing my comments on basic power supply engineering. I'll start a new thread on the bandwidth requirements of line cords shortly.Dpac996: Actually, what you want to use in that experiment is not a differntial probe, but a current p... | |
| how can a line cord affect frequency response ? After writing that last night, it occured to me I should also elaborate a bit. When I said bandwidth, I was speaking in terms of the amplifier bandwidth, and I still state that line cords do not affect it. But since we are discussing line cords, l... | |
| how can a line cord affect frequency response ? Regarding RF: I didn't mean to imply the line cord acted like an RF antenna when it was powered. What I was trying to say, however vague, is that it can act like an antenna and pick up RF energy. Although this energy should be eliminated in the tr... |
