GT-AUDIO-058
GENIE TECHNICS educational audio amplifier, 2 × 100 W RMS into 8 ohms, for studying, diagnosing and troubleshooting high-fidelity audio circuits. It is supplied with a complete schematic, a diagnostic manual, reference voltages at key points and protected test terminals.
Characteristics
- Continuous output: 2 × 100 W RMS into 8 ohms
- Total harmonic distortion: THD below 0.05%
- Signal-to-noise ratio: at least 90 dB
- Frequency response: 20 Hz to 20 kHz within ±0.5 dB
- Oversized toroidal or EI transformer
- Filter capacitors: 10,000 to 22,000 microfarads per rail
- Symmetrical supply: ±35 V to ±50 V
- Complete schematic and diagnostic manual
- Normal voltages identified at key points
- Signal-analysis practical work with oscilloscope and LF generator
- Protected test terminals and module troubleshooting documentation
- Design note: 100 W/8 ohms requires approximately 28.3 V RMS, 40 V peak and 3.54 A RMS per channel; use loaded rails near ±45 to ±50 V or require measured proof of another topology
- Non-contractual schematic illustration
