Alexan have a 100 watts rms amplifier kit. I have assembled it 5 years ago and still functioning today.
Ok din yun.....

depende sa design... sa enthusiast tingin ka, meron dun na mga 100 W pero iba2 design & upon doing the design makikita mo hindi pare pareho pag init nila... na-prove ko lang un sa class namin nung ngaaral pako, 5 groups kasi kami, puro 100W pero di pare pareho yung performance...

I never tested it at its full capacity, dahil baka batuhin kami ng kapitbahay namin hehehe. I normally use if for an hour. Di ako kasi gano mahilig sa music. But i didn't notice kung ganu maginit .....hmmm..matignan nga.....

i agree sa sinabi mo

pero gusto ko kasi maging project ung 100 watt na un

nga pala ung running led na sumusunod sa beat?

un ba ung VU meter na sinasabimo?

Here is one good power amp project > http://sound.westhost.com/project3a.htm
I have built it and it sounds great.
I also made this preamp from the same site > http://sound.westhost.com/project94a.htm
to wrok with the power amp. Ayos na ayos!

may schematic ako ng mga 100W
pero ikaw na mag layout ng pcb

pm me if interesado

Here is a PDF file showing the schematic and PCB layout I made. Please

Happy listening!

maganda yang incredible amp na design ng alexan. basta mganda rin pagkakagawa mo. nag buo ako nyan dati 4 channel sa isang amp. pang drive ng mga monitor ko. matatag sya at malinis ang tunog. nakikipag sabayan nga sa gamit ko na QSC amp. worth for your money.

isang brand ng amp kit na gold ung heatsink pero matibay rin.

insomartin · « **Reply #18 on:** May 31, 2009, 12:18:17 PM »

yung LM12 opamp gold die attached. hehe. pero hindi yung heatsinks ngayon ko lang nalaman din na obsolete na din ang lm12.

stock up na ako nang spares.

insomartin · « **Reply #19 on:** May 31, 2009, 12:29:24 PM »

LM12 amp.

i love these babies. this can turn your 500 watts peak speakers to dust.
output transformer is at lease 30-40v and 12amps. (small welding machine?)
and carefully filtered. add a capacitance multiplier if you want.

see datasheet.

it is also can handle 800w peaks at normal program material at 100watts. gulp.
