I remove te F, the value of mpsa29 are E 1.316 C 735, the other are E696 C620 take from basa to E&C

 

OK that's good. Did you install the transistors correctly as the pinouts are not the same for Q2 and Q8.

yes the board has orientation symbol

 

Just want to try and cover all the bases to avoid any more damage.
OK, if you are sure then it's time to turn the amp ON.

No problem bro! With the small board or without?

 

With the small board OUT

 

With the small board OUT

OK

 

OK

it does turn on, but still no click

 

So the relay is not activating when the amp is ON?

Also I have no sound now

 

That makes sense. Need to get some voltage readings in the circuit when you are ready.

 

With the black lead on ground what are the collector voltages of Q1 and Q2 ?

ok, but when you said that it make sense, do you refer to the fact that doesn't make sound?

I'm ready by the way

 

Yes it makes sense there is no sound if the relay does not activate.

ok

 

ok

Q8 1.800 the other 0 nothing

 

Q8 1.800 the other 0 nothing

sorry you said Q1 and Q2, Q2 is zero nothing I try Q1 now 2 mins

 

sorry you said Q1 and Q2, Q2 is zero nothing I try Q1 now 2 mins

1.172 on Q1

 

1.172 on Q1

I notice that if I touch the C leg on Q1 it does make noise and after few second I ear the relay clicking, with some vibrating noise, but only by touching the leg it doing it! Even tho no sound come out
