ok then...
now, i got the point...
im very sorry for asking too many questions...
im just 21 and im not an electronic engineer...
but i build my own amps for quite sometime...
thank you for the advice sir...
and i hope for more of your advice soon... 🙂

Nice clean work. I can't see is there any protection in this amplifier?

tnx for the complement...
there is actually no protection circuit built in to it...
only a fuse was attached to it on the output terminal... 🙁

ok then...tnx...
i already have your schematic diagram bout it...
it's such a poor amp...
no protect, no limiter, only the power amp itself... 🙁

Not poor 4 heatsinks, 2 fans... if it is in use than you add protect for speakers safety.
i see...
that would be nice...
but i don't have any protection circuit that matches this amp...

I think there are many protect circuit matches with this amp, here are simplest with triac.

If you have no "bump" from speakers when power on your amplifier then I sugest DC protect with triac.
No, the "bump" is a turn-on transient. You can't use a triac clamp on an amp that makes a "bump" when you turn it on, because it will activate. On an amp that comes up quiet, you can.
is that the sound produce when i turn the amp on???...clicking the power switch on makes my speakers sound like "toobbb", even if the volumes are zero...tnx
Any sound "toobbb", "twak", "bump"... anti-click on DC protect turn speakers on with 5sec delay becouse of that.
hi apexaudio
greetings can you give some tips where likely problems
can occur some voltage test points
1 checking pcb once again for wrong polarity ofcomponents and shorts
thanking you
