Prin 97 am facut intr-o cutie de PC un amplificator multicanal [ 8 x 70w / 8 ohm ] . Trafo toroidal de 750VA .Este superusor de lucrat intr-o astfel de cutie si variantele de punere a mufelor si celorlate reglaje ( daca sunt necesare ) sint nelimitate .O carcasa de PC se preteaza pentru racire prin convectie si chiar da rezultate . Amplificatorul facut de subsemnatul in 97 merge si acum ( racire -convectie ) intr-un magazin universal de 8 ani , 12 ore/zi .

Convexia este miscarea aerului.Daca e pasiva aatunci aerul "se misca singur" datorita diferentelor de presiune provocate de diferentele de temperaturaDaca e fortata inseamna ca ai un ventilator.Ar fi recomandabil sa folosesti ceva ventialtoare sau sa pui radiatoarele expuse unui curent de aer, sau sa le scoti inafara carcasei (asta nu ar fi practic ca ar mari dimensiunile care oricum sunt cam mari pt un amplif)
