Hello
i do have a hifi amplifier
two compoennet is geting hot very fast, as soon as i start the amplifier
On transistor had failed
I changed it , but as soon you start the power , it is getting hot verry
on the schema it is the Q5 ans also R10 is getting hot
Any idee , i did have problem to understand
R16 ,D5 look ok
i did have 15volt on U1 pin 15
on my bord R42,R43 and Q7 is missing or shorted somehow
see the file here
