« on: May 02, 2020, 02:24:47 PM »
Mga boss, pwede pong tulungan ninyo ako sa gagawin kong amplifier? Kumuha ako sa ibat ibang site para mabuo ang diagram: may preamp at tone and volume control kaya after ECQ unti unti ko na kasi siyang bubuuin pero tanong ko lang po
1. Papaano ba makuha ang wattage niya
2. Kaylangan pa po ba nito ng power amplifier para mabuo ito? kung kaylangan ano po ang maisusuggest ninyo na power amplifier na pwede dito at saan kaya ako makakakita ng diagram para dito

1) Few milliwatts lang yan kasi op-amo yang TL072.
2) Atuhan mo ang TDA2030, readily available at hindi mo na kakailanganin o optional yang TL072.  Up to 15W.

Meron kit ang Miyama na TDA2030.

pwede ring basic amp lang na tulad ng nasa linl, may basic computation na din yan para sa newbieng katulad natin  8)

so kaylangan pa talaga nito ng power amplifier? maliban sa TDA2030, ano pa ba ang pwedeng opamp na pwedeng idagdag?

Ano ba ang ultimate use mo para sa amp?  Unang-una, mono ba o stereo?  For mic or instrument including CD/DVD, MP3 player, videoke, etc?

Design from the back to the front- power amp to the input/s.

For MP3 lang 100-150watts lang ang kaylangan ko for education purpose lang. May nakita na akong power amplifier circuit para dito, yung BC558 (http://www.circuitstoday.com/wp-content/uploads/2008/03/150-watt-amplifer-circuit.png) pero di ako sure kung gagana ito kasi sa tuwing sinisubukan ko ito sa simulator ng circuit wizard, pumuputok yung TIP41A.
