grabe naman load mo sir
mas maganda kung dalwang 502 gagamitin mo
ung isa para sa bass at yng isa ay para sa instrumental at horn tweeter

^tutunog yan kaso matatalo ung woofer pro depende kung anung woofer ang ginamit mo mas fino ang tunog nung 3" na tweeter. i-suggest na parehong sub ang gamitin mo, ung dual impedance  |

Japeyk 502A Konzert...  kahapon me nagpaayos nito sa akin 8 output pero 4 na dummy ...matanong ko lang mga master nakita ko kasi ang component placement nito puede atang i-utilize ito na magtrabaho lahat ng outputs...sa nakikita ko ito yata ang mga critical points na dapat mabago [hula-hula lang po ] Drivers q2,q30 = D669a q8,q15 = B649a r3,r31,r65,r109 = 100 ohms [limiting resistor to collector of pre-driver C9014 -q9 & q25] z3,z4,z5,z6 = 27v zener 1w 32v-0-32v power trans pacencia na wala kase akong schema nito..naisip ko lang kase panay daw nasisira ito  meron ba kayong schema nung original...tnks! |

dapat c2073 at A940 yung driver master Woots29, ito lang ba ang naiiba sa orig?...sa mga resistors kaya..apat din ang source resistors nung japeyk at puede ring i-tap sa dalawang output pair...hindi ko lang alam kung merong ma-overload na pre-drivers [small to-92]... |
