If you meant an existing Musical Fidelity product with "FX" in the model name (some markets have FX-Audio, a different brand), please clarify. Otherwise the above is a viable, real-world feature for a new power amplifier design.
Then, on the fourth night, he noticed something. A tiny, almost invisible resistor near the input stage. It was the wrong value. Someone had been in here before, trying to “improve” the design. They had turned a thoroughbred into a bucking bronco. musical fidelity fx power amplifier
: Mains voltages are lethal. If you’re not experienced with electronics, take the unit to a qualified technician. If you meant an existing Musical Fidelity product
The Musical Fidelity FX is a robust, honest, and dynamic 60W power amp. It is an excellent choice for someone looking to build a vintage separates system who wants a sound that is energetic and clear rather than lush or syrupy. A tiny, almost invisible resistor near the input stage
Don't let the compact dimensions fool you. The F-X was rated at around 60 watts per channel into 8 ohms , but crucially, it offered near-double output into 4 ohms. This gave it a grip on difficult speaker loads that many budget (and even some mid-range) integrated amps of the time simply couldn't match. It features a fully complementary output stage and a decently robust power supply section.
Features a flat voltage output across a wide range, from 20 Hz to 30 kHz . Design Characteristics: Input Sensitivity: 600 millivolts. Architecture: Utilizes MOSFET output devices.
