This manual is a service manual for the Sony 5-channel power amplifier TA-N9000ES, which provides detailed instructions on product repair methods and schematics
This service manual provides detailed information for servicing the Sony TA-N9000ES power amplifier. It includes model identification, safety procedures, AC leakage testing, and electrical adjustment guidelines.
The document contains exploded views, wiring diagrams, a complete parts list, and specifications such as power consumption, dimensions, weight, frequency response, and speaker impedance. It also outlines disassembly steps and safety‑related component replacement rules.
| Power consumption (Front) | 115 W |
|---|---|
| Dimensions | 430 x 173.5 x 453 mm |
| Weight | 52 lbs 15 oz (24 kg) |
| Frequency response | 20 Hz ~ 20 kHz |
| Speaker nominal impedance | 4 to 16 ohms (NORMAL) |
| THD (Total Harmonic Distortion) | 0.013 % |
The AC leakage from any exposed metal part to earth ground must not exceed 0.5 mA (500 µA).
Leakage can be measured with a commercial leakage tester, a battery‑operated AC milliammeter, or by measuring the voltage drop across a resistor using a VOM or AC voltmeter.
Components marked with an “A” or a dotted line are critical for safety and must be replaced only with Sony‑specified parts.
