Sa ngayon temporary ko syang pinalitan ng ecaps,mula sa 2,200uf to 4,700uf/50V,wala pa kasi budget pambili :-) Medyo humina na yung ugong. Tsaka unti2 ng lumabas ang kicking bass :-) Pero balak ko pa rin palitan ng ecaps. Bale nung una,6 amper lang talaga supply ko,tapos dinagdagan ko pa ng isa pang 6 amper,parallel ko lang silang dalawa. Yun naman sa amp ko,kumuha lang ako ng supply dun sa booster. Kailan ba talaga separate ang supply ng amp?

Wala pa rin pambili malaking ecaps. Still using 4,700uf para sa 6amper na supply ng 100w booster ko.

@jimsky143,pra sa akin mas ok pa tunog kong mini amp with tone control ang gnamit mo.d mo kc mavary yong bass at treble sa simpling boster lng,kya magtunog lata to.khit gaano pa klaki ang output mo.pro,dpende na rin sa yo yan kong ano test mo.Very Happy tunog lata:ito ang term nmin dto sa cebu sa gaanong kagandahang sounds.kong audio hobbiest ka dpat marunong ka rin makinig ng audio quality.

Kulang lang ba supply ko na dalawang 6 ampers? Kasi parang hindi ko ma todo yung volume,parang kapos ang tunog pag tinudo ko ang volume. Or kulang lang sa ecaps?

regulate mo na kc supply mo:D yong an214 mo design kc for battery operation,at cgurado akong my tape preamp pa yan,at design ito to operate @ 9volts.droping resistor lng gmit sa preamp mo,kya ngayon lagpas ito sa 12v.[16-18v kc supply nto @ rectified dc]separate mo nlang yong supply mo sa amp.bali 6amp sa amp at 6 dn sa boster.yong suply sa amp lng regulate mo.sa method nto,d kna mamomoblema sa malaking ecaps.malaki na kc ecaps sa boster mo.

So anung pisa ang kulang dun sa 6ampers na supply ko sis para magiging regulated? Dalawang 6amper diode lang ang nilagay ko dun tsaka 4,700uf ecaps.
TIA sis arkin.

Salamat sis djfel. Dagdag lang na tanung,pwede ba to gawin sa 6amper? Bali dag2 nalang ako 2 diode na 6amp din para maging bridge. Tsaka yang dinagdag na pyesa,ciramic ba yan? Tsaka yung isa,trany yan? Pwede naba yan lang idagdag ko sa 6amper na supply ko? Hindi naba papalitan ng value? Sensya napo sis Djfel.
TIA po.

Tama ka sis arkin,12-0-12 trans4mer ko. So kulang nlng ako ng 7812 ic regulator na 3-5 amp sis arkin? Yung sinabi mo na iparallel dapat yung dalawang diode,12amp na kalabasan dun sa 6amp ko? Tama ba sis arkin?

@leurs,about sa diagram,ic nlang idadagdag mo sa suply mo ngayon pra maregulate,ok na yan.neglect nlang yong ibang parts.Very Happy about sa diode,pampatibay nlang ito sa rectifier cicuit mo.pro, sa observation ko,nkadagdag pa rin ito ng current output[kunti nga lng:D ]@djfel,pag comon at 12 lng ggamitin mo,3amp lng klalabasan nto.[teka,basic electronics lng ata yan ah:lol!:
