OCL 100 Watts LANEY here is a LANEY 100SC made of 90s.
This guitar audio amplifier comes with a 100 Watt audio output with 2 channels. The first channel is for High GAIN Channel, and another one is for CLEAN Channel.
High Gain channel is usually for guitar amps that tend to loud music like ROCK and Metal and other hard genres. CLEAN channel can be used to amplify the sound of guitar genre such as Blues, Country, Ballads, Jazz and other melodics style.

SCHEMATIC DIAGRAM POWER SECTION OF OCL 100 WATTS LANEY
This is the result of image edited of schematic diagram of LANEY 100SC:
From the schematic above, it consists of some block:
- Differential Preamplifier
- Voltage Amplifier
- Over Current Protection
- Driver Amplifier, and lastly is
- Final Quasi Power Amplifier.
TR1 and TR2 work as Differential Preamplifier. The circuit GAIN value is R6/R10 or 31x. Voltage source is 15VDC from D3 as Voltage Stabillizer.
TR3 (MPSA05) is Voltage Amplifier. C4 are capacitor boostrap for positive feedback signal.
This circuit no need servo driver. Its only using diode D5 and D6 to rectifying the audio signal to driver transistor TR6.
Tr4 and TR5 work as OCP. Its will be shortening signal to ground if there are over current flowing through power resistor R18 and R19.
OCL 100 WATTS LANEY using transistor BD909 in Quasi connection as Final Power transistors.
