^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 ;D

Japeyk 502A Konzert... :o

kahapon me nagpaayos nito sa akin 8 output pero 4 na dummy ;D...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 ;D]

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!

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]...
