di ko rin alam boss kasi nakoha kulang ang circuit na yan galing sa thread ni sir roland yan daw ang pioneer na circuit ginawa ko ulit. kaso hindi ko alam ang value ng isang transistor..

para sa VAS ba yan, pwede ka gumamit ng ibang transistor pagwala kang nakuha na 2sc1775.

di kaya pareho lang sa q5?

Johannah Aleksandria · « **Reply #14 on:** October 12, 2011, 01:39:49 PM »

Match na tranny yan sa Q4.
Pero yung Q4 ay pwede na ang BD140 at yang Q9 ay BD139.

Roland · « **Reply #15 on:** October 12, 2011, 01:46:10 PM »

tama si johanna, Q9 and Q4 are complimentary but will work fine even not complimentary. BD139 and BD140 can be used, pwede rin Q4=A940 and Q9=C2073.

vic24lordsf · « **Reply #16 on:** October 12, 2011, 03:06:42 PM »

salamat mga master sa tulong nyo ha..

+1 sis jonah at sir roland slamat maraming pa akong taong sa inyo after na ma connect ko natong mga component at sa pag troubleshoot ko nitong amplifier sana di kayo magasawang tumulong thank you....

vic24lordsf · « **Reply #17 on:** October 12, 2011, 03:09:36 PM »

gagawa nalang ako ng layout ngayon ... salamat ulit sa inyo ....

edtechph · « **Reply #18 on:** October 12, 2011, 05:25:39 PM »

di bd139 pwede dyan? d pwede sa Q4 b546a and q9 d401a?

vic24lordsf · « **Reply #19 on:** October 14, 2011, 01:16:43 PM »

mga master tama po pa ang mga value ng mga component na yan... lalo ng mga rating ng voltage ng capacitor at mga wattages ng resistor... gusto gus sana supplyan ng 80 volts/20amps na power supply,.
