| Point to Point Wiring Two main reasons in addition to the ones you stated: one, is to keep the chassis size to a minimum, and two, for production consistency. No two people have the same soldering skills, and can even have a bad day or two. But the pcb stays consistent... | |
| Amp heat sinks are ringing Goldmund understands and addresses this problem.. http://www.goldmund.com/old/Millennium/mechanics.htmlUnfortunately, finding someone to make a heat sink clamp out of brass or aluminum ain't gonna be cheap 'n easy. | |
| Does it make sense to upgrade ML 31 to 31.5? Depends on the gear behind it - that goes a long way in determining "significant difference". | |
| Popping Sound Coming From Speakers Everyone who has ever owned an electric guitar knows exactly what it is - time for a new cord. In your case, it's another pair of AQ's (trade them in - you got a bad one). | |
| What the heck are "zobel" circuits? Basically, it's an R/C circuit shunting the amp output to ground. One problem amplifiers have is the instability resulting from low frequency signals. The amps will oscillate at a high frequency when there is no inductive load at the speaker. The ... | |
| CD playing Rituals Whatever ritual you perform, always handle the cd's by the edges with clean hands, put them in the case immediately after playing, and back to the rack (away from any sunlight). I have some cd's 15 yrs - and they and all others look like new to th... | |
| Buzzzzzing Transformers Solid state amps usually have toroidal transformers. If they buzz, I would suspect RCA interconnects, dimmer switches, flourescent lights, and maybe (maybe) the turntable motor. Start by a process of elimination. If the amp by itself (nothing atta... | |
| UL certification and insurance They do, it's just they are not readily visible. The UL certification is for the plug and connector, not the whole cord per se. Plugs have to meet basic UL standards (UL 498) for electrical devices. The cord manufacturers do not make the plug/conn... | |
| wire for dedicated 20 amp circuit Maybe Romex is not permitted where you live, and that's why he came up with it. Ask. Aluminum MC will better shield against power line noise from external magnetic/electric/radio fields. Probably the best off-the-shelf wiring you can buy for audio... | |
| OTL amplifiers OTL's are usually more expensive, have many tubes - expensive tubes (high current triodes), consume a lot of power, may not perform the same with different speakers, and may not even work with some speakers. Those are, in very general terms withou... | |
| 30 Amp Breaker Question Branch wiring to to 120-volt lights and receptacles have to be on a 15 or 20-amp circuit breaker, but the wire can be any size greater than #12. That's the code - whether you choose to heed it or not is your business. General-purpose receptacles a... | |
| DC offset level to avoid speakers damage- The maximum dc offset tolerated by a speaker is a percentage of the linear excursion of the driver that is acceptable, usually 10 to 15%. The formula used is:Vdc(max) = % excursion x excursion x driver impedance/[Force Factor x Suspension Complian... | |
| Passive parts: Do they make a difference ? Sean: an interesting question begs to arise - give me a box full of the best passive devices, and, if I were to build an amplifier (a rank amateur, me) how would it sound next to an amp built by, say, Nelson Pass with Radio Shack rejects? I do not... | |
| Is there an advantage to more tubes in an amp? Tubes are also called "valves" for the reason they act like water valves. Think of the power supply as a water reservoir and the speakers water turbines. The more water that hits the turbine, the more the sound power. If you have only one valve, t... | |
| dedicated amp outlet vs avs 2000 You could try a wiring/raceway system called "Wiremold" which is a wall mounted decorative raceway that runs flush with the base molding of walls. Even the outlet boxes are surface mounted. This avoids cutting behind and into walls and I've seen t... |
