| Autoformer vs Speaker impedance Curve I note that this discussion has many questions concerning the use of an autotransformer with high damping solid state (voltage paradigm) amplifiers. I would say there is little to gain and a lot to lose using one. Here's why. This does not apply t... | |
| Autoformer vs Speaker impedance Curve I design and manufacture audio transformers for all Music Reference amplifiers. I also make OTL amplifiers with and without autotransformers which actually extend the frequency response in the high end. Here are a few things to note. An autotranfo... | |
| Amps and Preamps has standby, but should I turn them completely off? Guitar amp power is usually measured at 5% THD. At low powers they can be quite clean. The older brown face Fenders were really clean. This was before Hendrix and the craze for overdrive, which is just another name for clipping/limiting, turning e... | |
| Amps and Preamps has standby, but should I turn them completely off? The reason electrolytics need to be brought up slowly after a long sleep is because they will exhibit leakage current which multiplied by whatever voltage will produce some watts of heat. I dont think ESR is the main factor in caps exploding. It i... | |
| QUALITY AND SECURITY OF "LITTELFUSE" PRODUCTS The reason tuning fuses are unsuitable for fusing tubes is quite simple. When a glass fuse blows in a DC circuit a plasma is formed in the glass cylinder. This plasma continues until the power supply has dumped all of its energy into that tiny fus... |
