eh project din sa kaibigan ko b4 binigay lng sayang nmn kc may 3v - 12v selector..ano po pwd bibili nlng ako bago transformer at ako nlng assemble ng full wave.?ganda umaga pala sayo at sa lahat nka OL.

bili kana lng,ok na 10 amp.sayang lng yon masyadong malaki,damihan mo lng diode,pra matibay supply mo.hwug rin masyado malaki voltage rating ng capacitor.ok na 25v.

fiftenwats,dami yata ng input mo,pro kunti lng resistor mo.ano setup ng input mo,paralel lng in at out,tsaka bias?

bumili kanang an 214 na ic amp yan yong gawin mong pre amp driver or gawa kanang 4558 jrc na pre amp para magawa mo ang 3way tone control

bale yong setup ng input mo.dba 2 input gamit mo per chanel?nakaparalel lng ba lahat to?[sa mono side lng ha]mula sa input mo[galing sa amplifier]patungong transistor.ilang resistor ba gamit mo lahat2?[mas madali cguro pag ganito tanong ko] Very Happy

dalawa lang po kagaya nung schematic the difference is yung input transformer eh naka series

sa tingin ko mali yong gnawa mo?[series ba talaga o paralel?pkiguhit nlng cguro pra mkita ko mabuti Laughing sa tingin mo malakas ba sounds mo?san mo nkuha yang ganyang setup?pwede post mo rin ano gamit mo driver sa booster mo.nkagawa na rin ako ng ganyang setup,pro ibang-iba sa gawa mo.

salamat po..gumagama po yong booster ko pro di nagtagal kc parang scratchy..mainit po yong isa kong power transistor ano po yon?siba ba??

ilang transistor gamit mo per chanel,kong 2 lng per chanel talaga magbabaga sa init nyan.kilangan dagdagan mo pa ng transstor pra d masyadong mainit.o d kya,plitan mo resstor mo sa ground,taas mo ng kunti.kong sinunod mo yong nasa furom nato,dapat plitan mo 500 ohms.

paano ba pag distorted ang sound ng booster pag hinaan ko ang volume? anong parts ang papalitan ko o change value nga ba ng resistors?

plitan mo ng mas maliit na value yong resistor sa ground.dka marunong ng V.D.F.?mas ok if marunong ko non,kc mdali lng maresolve yong ganyang problema.ano value ng resistor mo sa ground?clue:if 500ohms rsstor mo sa grnd,baba mo kunti,cguro mga 470.depende rin kc yan sa dami ng transstor mo.

ito po yung kadalasang setup dito sa amin dual input transformer.
yung pinagdrive ko po is yung pioneer KP500 na head unit,
hindi ko po ginagamit tong booster ko, wala naman akong sasakyan eh Very Happy
ginagamit ko sa bahay ay power amp :albino:

taga cebu din ako tol.nkagawa na rin ako ng dual input.nsubakan ko na ring i-series,akala ko rin npa2lakas sounds sa gnitong setup,mali pla.lalo lng humihina sounds ko Very Happy .bakit?kc,nahahati lng yong input.gaya sa speaker,pagnkaseries humihina,pag nkapralel lumalakas.sa setup na to klangan mataas bias[maliit value sa ground resistor]kc distorted sounds sa low level volume.

salamat po master. +1 sayo subukan ko na lang
