Hi,
First of all you have to check The positive and negative 95V in the collector pin of all output tansistors. There should be +95V in the all collectors of MJ15024 and --95V in all collectors of MJ15025 poer the output transistors of faulty channel.ANd tere should be +/-- 0.5 volt in all output transistors base pin. All emitter pin should be aproximatly 0V. If not then you have to check the tansistors Q13 to Q16 and Q17 to Q20. Also the driver transistors Q9, Q10, Q11,Q12,.
If you need the schematic diagram that i will sent it to you.
ok
Testimonial: "Thamk you so much for this information, it would be great if you send me the diagram, [email protected]"
Hi there.
have you checked the internal fuses?.if one has blown then replace it.then,if it fails right away,then it fair to assume short circuit output transistors etc(one of which you mention)
good luck!
