MBL 8006 clone

July 21, 2009 - filed under: Other Amplifiers

This is a clone kit from China.  It is a class AB amp and the clone is only for the power amp part.  The measured result shows a very good design amplifier!

1. Gain: 18x
2. Supply Voltage +/-50V; with 36V x 2 AC transformer
3. Distortion at 1W 8.2ohm: 0.0044% 30kBW
4. Current drain at idle: 160/153mA.
5. Current drain at 1W output: 260/253mA
6. Op-amp: 4.5mA
7. 470 ohm resistor: 1.75mA
8. 33 ohm resistor: 24mA
