One thing you will definitely need is a suitable amplifier. Ideally transistor then impedance matching is not an issue. Also you do not want to kill your speaker. Something that puts out about 15 to 20w is ideal for testing old greenbacks. Remember that transistor amps only put out their h...
5F1 Champ Guitar Amplifier Layout DiagramI added component numbers to this layout that match the schematic diagram below. Compare this to the picture of the chassis above. I have had questions about the grounding scheme shown in this layout. Grounding the V2 power tube grid leak (R9) and ...
Most PA power amps are designed to handle speakers rated at 4 or 8 ohms with some that handle 2- and 16-ohm loads also. You’ll note when reading power amplifier specs that the rated power output decreases as the impedance (ohms rating) of the speaker increases. For example, theCrown ...
If you have a really old amplifier, or something particularly obscure, it might be best ringing ahead to make sure the dealer has something similar in the shop. If not, take your own with you; yes, it’s going to be irritating, but anything’s better than one of those “they look no...
s coil can handle before it melts down. So, amplifier power output shouldn’t exceed the power rating of the driver for too much. And to little power from the amplifier will usually make us turn the volume knob until the end and that will make the amplifier clip, which will also damage...
The ADC and system requirements for an RTD measurement system are quite stringent. The analog signals generated by these sensors are small. These signals need to be amplified by a gain stage whose noise is low so that the amplifier’s noise does not swamp the signal from the sensor. Followin...
If, on the other hand, you perform at parties and places where there’s no sound system, you’ll need to have your own amplification system and speakers. In that case your best bet will be to go with powered PA speakers, which eliminate the need for a standalone amplifier....
In simplest terms, a gate driver is a power amplifier that accepts a low-level, low-power input from a controller IC (usually a processor) and produces the appropriate high-current gate drive at the necessary voltage to turn the power device on and off. Behind that simple definition is a...
Does an Anodized Red $200,000 Amplifier belong on the Front Cover of a magazine like ours ? None of us will ever have any chance to experience Velvet Rope Gear so why are we bothering with it? It being better is probably one person's opinion ( and that person probably doesn't have ...
If you still don't get any output from the amplifier, disconnect it from the speakers in your vehicle and hook it up to a known good speaker that isn't in your car. If the amp drives that, the problem is with the speakers or wiring. If you still don't get any sound, the amplifi...
