Troubleshoot notes:
1. Power specs:
a. 8 ohm: 500 W = 63 Vrms, Input sen = 1.2 Vrms
b. 4 ohm: 700 W = 52.5 Vrms, Input sen = 1.00 Vrms
2. Output gain: 34.4 dB = 52.5 Vrms
3. Idle current: 0.3A; short limit current: 3.3A /CH,
6A /2CH (120V unit)
4. Amplifier would start with an AC voltage above 50 V.
