Pa help po sa Audio Amplifier

[kenshee]

Our professor required us to build an Amplifier (transistor based).

100Watts ung output. anything that shows amplification. kahit ano po ung input. mapa mp3, mic, receiver etc. Ang labo pa po kc tlga in my part. Any concepts or basic ideas po? Para maliwanagan lang na kaunti. hihi.

Thanks!

kenshee,

What I am about to say is to help you. Not to offend you in anyway.
If at this point you have no basic idea about an amplifier - talagang malabo - it is not recommended to build one. You will waste your money, time and you will learn nothing. There are 2 sides of the coin here. Your professor is not a good teacher or you need to work harder as a student. I suggest you determine which side is the problem then do something about it.

If you noticed, nobody has replied to your post for quite some time now. It is because it is not easy to help somebody on a relatively advanced subject when that somebody do not have the basics. Once you have the basics, many people in this forum can help you. I hope you understand this.

besides,

a 100W amplifier is too much
for a beginner, i would suggest start from a 2 watts lang,
basic transistor amplifier.

[kenshee]

ahhw words of wisdom from the masters.
ill do my best. ill come back with a diagram and some queries po.

thanks for making me aware.

[danny]

just post your questions
im sure madaming tutulong sa iyo dito
don't get upset in case na mabalahaw ka
it will be ok naman in the end

kenshee, look at eh alexan kits. may mga audio amps.. dun. di ko lang alam kung hindi IC. For a begionner, wow, ang tass ang 100 watts.masming akon schem for lower power..

[kenshee]

sir BK thank you po for noticiing .
Our prof changed it to 40W and above na po. we've searched schematics from the net and sa alexan books.

Problem is, we are kinda worried po kung san dun ang i papasa bka po kc may mga transistors na di available d2 sa tin.

I would like to request po all mighty sir BK kung meron po kaung na daanang audio amps greater than 40W or greater po. We'd like to ask for ur recommendation po.

[catcha03]

parang project lang din namin, >100w nga lang, suggest ko pag aralan mo yung BJT Transistors pati yung mga NPN and PNP types, tsaka modes of operation...

[kenshee]

ok maraming salamat po.

[danny]

ok maraming salamat po.

try my 40W amp
may na post na schematic dito
actually tested na din yun

sana makatulong 

[Woots29]

at may mga video din

[kenshee]

wow. thank you po, dun nlang po ako refer. maraming salamat po ulit mga masters!

[danny]

patulong ka kay woots
sa pag assemble bihasa siya diyan 

[Woots29]

^sir naman. di masyadu

[neutron]

Woots = mighty assembler

[Woots29]

^baka mighty bond
