Está mal conectado jamás debe ir el positivo de la fuente o cargador a la patita del medio del transistor que es colector es un drenaje hacia afuera no hacia adentro entra voltaje por la base adentro del transistor interactúa se activa junto con el emisor y sale voltaje y amperaje por el colector por eso en ingles se llama Drain ( Drenaje ). Por lo tanto recalientas el transistor hasta quemarlo o dañas la fuente de energía o cargador. Adentro del transistor en el colector va el polo positivo del diodo y la linea negativa del diodo va apuntando hacia afuera del transistor llamándose lado negativo,Y NO OLVIDEMOS QUE UN DIODO EMITE SU TENSION E INTENSIDAD EN UN SOLO SENTIDO POR LO TANTO SI ES SALIDA NO PUEDE Y NO DEBE VOLVER VOLTAJE E INTENSIDAD CORRIENTE ,PORQUE JUSTAMENTE ES PARA ESO UN DIODO,SI NO RESPETAS ESA POLARIDAD SE QUEMA.

Real Amplifier

[@analogaudiorules1724]

Shouldn't these eletrolytic capacitors be bi-polar? I'd also like to mention that tieing the left and right positive input cables together coming from whatever your source is, is a bad idea, thats basically shorting both positives together, which can damage you're source, you should put one 1k resistor for each input wire before combining them so there is at least some resistance between them... one for left channel one for right.

10" doesn't matter, should be 4 ohms. If ohms are greater than 4 then join two speakers in parallel. For example, if you join two 8 ohms speakers of any size in parallel, they will become 4 ohms. Thanks for watching & comments.
