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

translation: me nagawa daw s'ya na stereo booster , tumunog daw but it needs "*timpla", tanung nya kung sinu marunong mag modify ng sound ng booster

note:
"TIMPLA" refers to modification of booster, to produce more bass/treble by adding secret daw na mga resistor at caps, sometimes the output transformer is modified
"KWADRO" is a type of booster which has 4 channels, ginagamit ito mostly sa gubat gubat (decibel wars) sa cebu ;D

mga masters... ask lang ko ba bahin sa ako booster... init man jud xa pag ayo.. akong output kay 200 nya bale 32 kabuok mj 2955 nya ang pag bias ani kay 10wtts 200 ohm 2 pcs. ug 10wtts 10 ohms 2pcs. asa man akong pagamyan or padak an nga value ani? stereo diay ni akong na himo mga master... na lipong nako sa aso sa led... jejjejejejee salamat daan ninyo mga master... naa jud ko nakat onan ani nga site... more power.........
