this video is about how to modify the power ocl 150 watts so that the bass is steady, by using
small travo bass sound steady and kicking, just replace a few transistors
bd193 replaced with mje340 / bd140 replaced by mje350 / elko 47uf 25v replaced with 47uf 50v /
Elko 1uf 50v input is replaced with a 100n capacitor, the 0.5 ohm 5watt resistor is removed and
run or screwed using a cable, adding a 12k resistor for parallel to the 33k
even though using a small travo but the sound is steady and kicks.
