| System to system No, the unpowered/not used amp would load down the powered amp and depending on the circuit could actually damage it. | |
| OpAmp Swap? They are not pin to pin compatible, the OPA2604 (not Chinese but made by Burr Brown not owned by Texas Inst.) is a dual (2 op-amp in the IC) and the OPA627 is a single. | |
| Class A, AB Example to explain:Class A: If amp peak current is 10A then with no signal all 10A flows thru the + rail transistors also the - rail transistors and none thru the speakers. At half power 5A flows thru the speakers and 5A flows thru 1 of the transi... | |
| How to install a 120 Volt Cooling Fan? If you run a 230vac fan at 110vac, it will run very quietly. | |
| Help with math and science of tri-wiring? Amfibius,The impedance of the individual sections of your speakers was set by the designer to have the correct volume when the same voltage levels are going to each section as when they are not bi or tri-wired. If you want to bi or tri-wire then y... | |
| Help with math and science of tri-wiring? I would think that they all need to be connected to the same tap. This is because:each "ohm" tap is to allow for the same amount of power to match the paticular speaker. For example the 8 ohm tap will supply more voltage but less current than the ... | |
| Nuforce v2: has anyone tried them Denf,have you compared the NuForce with the Spectron? | |
| Amp Designs That Are Able To Drive 4/2 Ohms Load Watts = voltage x currentWatts = voltage squared / resistanceWatts = current squared x resistanceThe max voltage of a amp is limited to its internal DC supply voltage.If the wattage does not double when the resistance is cut in half then the amp i... | |
| Spectron Musician 3 First Impressions? Can the Spectrons be bridged? As a switching amp, I would think that it is already operating in a bridged mode. This can be checked by (with power off and speakers disconnected) taking an ohm meter and measuring if there is continuity between the ... | |
| Motorola transistors The actual part #'s are MJ15......The MJ15003/4 are 20A, 150V, 25 min hfe, Ft = 2MhzThe MJ15022/3 are 16A, 200V, 15 min hfe, Ft = 4 MhzIt will depend on the actual amp design as to whether or not this swap will even work, much less give an improve... | |
| The importance and effect to and above 20kHz... While we can't hear above 20khz, any sound content above 20khz could interact with other sounds and the resultant interaction create sound that are the difference between the 2. For example, 20hkz and a 22khz interacting together would create a 2k... | |
| Integrated Amp for VR4jr I have a Musical Fidelity A308 which does pretty good at 150W. | |
| superphon revelation To confirm the capacitor voltage requirements, before you get the replacement caps, measure the voltage across the existing caps. If it is less than ~ 14VDC, then a 16V rated cap would be ok. I wouldn't use an electrolytic cap above 90% of its rat... | |
| Lead shot VR4jr's Jdodmead,The old version of the spikes were thin hour and glass shaped while the new ones are tiangular shaped about 1 inch wide at the top. The old ones were black coated brass and I assumed that the new ones also were, I'll need to check. Also, ... | |
| Lead shot VR4jr's I'm the person Aball mentioned. I contacted my dealer and he was able to get me the new version of the spikes from Von Schweikert for free. I also have hardwood floors and set my spikes onto homemade pads to protect my floors. The pads consist of ... |
