LANEY CP12 is an OCL 250 WATTS LANEY, an Amplifier Monitor made by LANEY that it is using symmetrical 52 VDC and MJ15003/MJ15004 TO-3 transistor as Final Power Amplifier.
In the brochure they said that its design for a 120 Watts Power Amplifier even though it uses 250 watts transistors.

SCHEMATIC DIAGRAM OCL 250 WATTS LANEY POWER SECTION
The following is a schematic diagram of the Power amplifier section of the LANEY CP12 after editing:
From this circuit OCL 250 WATTS LANEY we can find out if it consists of several blocks, including:
- Differential Preamplifier,
- Voltage Amplifier Stages,
- Servo Driver,
- Over Current Protection,
- Driver Amplifier, dan Lastly is
- Final Power amplifier.
Final power transistor use MJ15003 / 04 and this is able to make 250 Watts audio Power output.
