Now measure from ground to the collector and emitter of Q10 with the ohmmeter at the 200 setting.

You got to keep in consideration that it was working perfectly prior my mistake, and it was exactly installed as it is now with the protection, it blowed because i did short 2 pins in the TDA

Now measure from ground to the collector and emitter of Q10 with the ohmmeter at the 200 setting.

Set the meter on 2K and read again please.

emitter, collector or base?

 

All three leads.

 

I have some things to do here shortly so will be in and out on the Forum. Happy to stay with you on this to get it fixed. Be patient and don't turn on anything until we get some more data.
