Clarification lng po sis arkin. Ic regulator nalang idagdag ko,tapos ang value ng ic ay 7812 lang ba? Ito lang ba sasabihin ko pagbibili ako? Pero yung 5amper or kung merung 6 ang bibilhin ko?

@leurs,kng my mhanap kng LM350T or LM338k mas ok,kc nsa 3amp ang 350 at 5amp nman ang 338.kya lng variable ang mga to.anyway mdali lng nman to.chek mo na rin sa internet for aditional info.my kmahalan din mga to.Very Happy kong gusto mo ng mura 7812 nlang gmitin mo.sundin mo na lng lng yong diagram na bigay ni djfel.take note,1amp lng yon.pro na try ko na rin n isang 7812 lng gmit ko.pro pwede mo rin eparalel ang 7812 pra mas mtaas yong curent output.yong sa akin 3 gnamit ko.nlagyan ko lng ng .5ohms resistor sa input,tapos paralel ang ground at output.prang my post na yata c ultra regulated suply,d ko lng maalala kong san:D my tranys yon,kya expensive.lol!

@sis arkin: Kung sakali hindi ako makahanap at makabili kasi may kamahalan ang sabi nyo. Sa 7812 nlng ako,so pano,sakaling magparallel ako ng 3 nito,3 ding .5 ohms gagamitin ko para sa input?

May extra power suppy ako dun sa bahay...yun nga lang 1amp lng yun,pwde ba yun sa amp ko gagamitin instead of my 6amp? Dun ko nlang ilagay tung 7812. Pwede kaya. Smile

Hello guys Im new here: i need help:

I want to make a stereo booster amp.

i have a (Tx 200V - 0 Vin) (12 0 12 Vout)

i want to make a stereo amp. 2 channel:

ask: ilang watts po ba dapat ang output Tx ang gagamitin ko,

if 100 watts na output Tx?
ilang watts po ba ang speaker na bibilhin ko ex. ang range
ay 100 - 300 watts na 4 - 8 ohms speaker, ok lng ba sa 100
watts na output TX ko o hindi?

sagot:



at ilan ung IC amp. ko ilang watts ba ang dapat dito Po?

pls help me guys, thanks a lots for any comments you share with me...

god bless po ... Very Happy

tama!!!!


watt is the unit of power or work...
and then if the loads needs more of it..
the more work will produced in transfo...


if mo init na syag maayu it means taas siyag gi work sa load....

super laughping  a lot of off topic answers.

Q: ilang watts po ba dapat ang output Tx ang gagamitin ko
A: Depede kung gusto mo ng malakas o mahina na amp.

Q: if 100 watts na output Tx?
ilang watts po ba ang speaker na bibilhin ko ex. ang range
ay 100 - 300 watts na 4 - 8 ohms speaker, ok lng ba sa 100
watts na output TX ko o hindi?
A: ok lang ang load na 4-8 ohms @ 100-300w sa 100w na output Tx

Update lang mga sis,separate ko na yung dalawa ko 6amper na supply, 1 sa amp 1 sa booster. Pero hindi ko pa rin na regulate yung 1 supply para sa amp,dinagdagan ko lang ng ecaps na 10,000uf pati na rin yung supply sa booster. Tanong ko lang, bakit kaya ang init ng trafo ko sa supply ng booster? Natural lang ba to mga sis sa mahabang paggamit? Yung tranny mainit din...

syempre 6amp nlang yan,tlagang iinit ng husto trafo mo.lalo nat beyond normal limit ka kong magpatunog nto.sa trany,klangan mong plitan bias mo.taasan lng ng kunti yong resistor to ground.

Ganun ho ba,sabi sa ibang forum,mga 20amps daw na supply eh ang mahal na ata nun.hehehe. Sa resistor sa ground 200 ohms yun. Anung value kaya ipapalit nun?

masyado na tlagang mlaki yong 20:D ok na yang 6amp basta normal limit lng sounds mo.[perti sad cguro nmo mkabunal:D 3amp lng nga gmit ko non,2 chanel boster at amp.]cguro 10 ohms sa b+,plitan mo ang 200 ng 270 or 300.4 ba gmit mong speaker?bale 2 per chanle,tama ba?kong tama ako,talagang maiinit yan.dont panic,ok lng yan.
