crate bx25 bass amplifier

nagtataka ako bakit ang hina ng tunog e 50watts ito 10inches ang speaker e mas malakas pa ung sound ng cp ko d2 sa bass amplifier ko,, nong buksan ko,, ayun may sunog na resistor ung r23 connected po sa tda amplifier,, d kona kc makita ung value mga bossing ano kaya possible na value nong bossing fusable resistor lang ba un mga sir ok na po ba ang 5ohms na 1/2watt>>>?? malamang tinamaan din c TDA d2?? buti nalang good ang speaker,,at wala naman sayad

R32 po pala ung sunog,, nagtinig ako ng diagram ng mga tda2050 e halos nakkita ko na connected resistor sa pin 2 ng TDA e 22Kohms,, possible po kaya un din ang resistor na sunog???

Palitan mo muna ung resistor, kung ganun pa din, then thats the time to replace the IC,
common naman yan sa mga electronics stores :)

i think its the 680 ohms resistor and check nalang yung capacitor connected to that resistor or better replace nalang.

andyan pa kasi yung 22k resistor R30

tama ka 680 ohms nga yan kasi feedback to ground yan nakaseries sya sa cap na around 22uf or higher and value....mukhang nag oscillate yan ah...
