Tanong ko lng ulit kung okey lang ba gawing 5.6k yung 15k resistor na naka series sa bias diode na nakalagay sa base coleector ng bias transistor 2N5551 SA WESTRAK AMPS?Salamat po...

Gusto ko lang mag tanong if this is  speaker (Paudio IMF-HP18s) is good for a westrak amp or should i choose crown jack hammer JH-181, TNT 1000 watts or live 18 pa-1000watts. Gusto ko lang malaman ang opinions nyo lalo na for PA and disco, Baka magsisi pa ako sa huli. Elco kit ang gamit ko ngayon pero try ko sana ang westrak. For now I want to try yung IMF from paudio. First time ko kasi mag buy ng 18inch speaker for sub purposes kahit two pcs lang muna.

with triple Darlington, your VAS will be loafing all the time...really depends on the drive requirements of the output stage

what i mean is, your VAS will just be swinging voltage only, current delivery is very very small....

umaanghang mata ko sa kakabasa ng 43 pages heheheh.... may nagawa akong ampli dati 100watts gumana mga ilang araw pero nung nasunog ang resistor transistor nawalan na ako ng gana kasi wala ng pambili ng pyesa studyante pa lang kasi tapos wala rin mapagtanungan kung ano problema ano mali ano problema.... may natutunan din ako dito, kasi open yung mga expert dito, kungbaga pag may problema pwede agad itanong sa experto...

kudos to the masters.... sir tony, bongtech, johannah, at sa mga di namention na experto... saludo ako sa inyo... :)
