what i meant to say is baka maguluhan sila, kasi marami yung 12v at GND Very Happy Very Happy Very Happy

ibaba ng kunti yong ground resistor.example:470ohms,gawin mong 400ohms.kung masyadong mainit yong pwer trans,itaas mo yong value.

korek ;D
may naka-encounter na sa inyu nga ang bass & treble niinit kaayu ?
unsa kahay daut ani sir?
naa gihapon sya music kusog man sad pero init kaayo ang pre-amp ??

Yung TR1 ay RDL-I at yung TR2 ay RDL-O. 33 ohms at 270 ohms na resistor @ 1 watt . Sa Raon pa kami bumibili noon. Sorry medyo matagal na kasing project namin yan sa high school at di ako sigurado kung may gumagawa pa ng ganung transformer. Actually yung ginamit naming transistor noon ay Genuine na 2SB449 o 2SB337. Resistors are 4.7 and 470 ohms. That was year 1979 pa.

yung booster na ginawa is 50w yung output nya,masyadong mainit yung transistor(MJ2955),my R1(22ohms-5w),R2(330ohms-5w,pero hindi naman nag aamoy sunog yung transistor kahit npakainit nya,normal lang ba yun?

masyadong mataas bias mo,d na normal yan.intayin mo pa bang masunog pra mag-amoy sunog? aware plitan mo r2 mo,mga 450ohms-500ohms,depende sa dami ng trasistor mo.

try this

audiophonics dot com

similar to our pinoy booster, but this is way better.
It will put our booster in the dust.

observe the limits of the outputs

minsan share ko din dito yung
40W na amplifier ko
I will make a thread for that one.

stay tuned

at ilang ohms din ang gagamitin dito?
di na ba ntin kailangan gumamit ng caps dito?
