mukhang gaynclone amp toh ah TDA???
ung heatsink maliit yan ;D

TDA2030 po yan plus may 4558D na tone control bass,mid,treble,

another question is kasi yung 4558 max nya ata is +18v eh ang supply ko is 20.25v okay lang kaya yun?

yung heatsink meron na po ako malaki, di ko palang po nabutasan hehe.
I love to make DIY's,... but I need your helps.. :D

Idrawing mo yung traffo output mo sa ps then paano nakakabit sa amp mo para makita ng mga masters natin.

sa simula pwede 'yan, pero kapag tumagal masisira din 'yan.

masyadong malapit 'yung voltage rating ng ecap sa voltage mo, kaya kung pangit 'yung ecap, unti-unti talaga siyang lolobo. ;)

so dapat po mga 50v yung cap ko?


plug ko po ulit yung ampli. gumagana po, lakas lang ugong parang may grounded pero nawala din, yung capacitor naririnig ko yung pag LEAK ng liquid sumisirit yung tunog

pede po pala yung 20.25vdc pwede gawin 16 volt using resitor lang?..verify lang po sa mga master
before you judge me..make sure that you are perfect

^ pwede, pero hindi laging parehas ang boltahe mo sa paglagpas ng resistor, depende kasi sa current ang voltage drop ng resistor.

regulator ang ginagamit kapag ganyan.

since local/hindi branded 'yung capacitor, use a higher voltage one, merong 35V or pwede ring 50V.
