SOLUTION!!! Treble broke bass sember | modif socl 506 | 504 | ocl 150 | safari 400 watt great bass
Modification of the OCL power amplifier driver which is very simple and the cost is quite cheap, for the results it does not disappoint (overcoming the broken treble Socl / OCL driver, bass sember) we only modify it slightly but the results are very full power, before modification we first check the final power bias teg the amplifier when it is sufficient / reaches a minimum bias teg of 0.45v can maintain or increase the bias teg again in order to produce mid high low sub sound with full power (steady bass), we increase the bias only adding a resistor to the three diodes embedded in pcb diode which is connected to the pnp base leg and npn transistor driver, we remove one of the diode legs and then we draw it with a 47ohm - 1k resistor, just choose the desired bias voltage. THIS MODIF CAN BE APPLICABLE FOR SOCL 506-504-6 OCL 150 WATT DRIVER AND 400 WATT SAFARI... HAPPY TRYING
(THANKS)
