Hi when i have this amp,the amp turned on but did not produce any sound, so i opened it and i found a bad transistor (D600) and a diode, i replaced them and and tested now the power led blinks..i can't find any other bad component. Does anyone have had the same problem and fixed it.? please give a hand.?

Have you compared the voltage on those 3 transistors to the voltage listed for them in the service manual?

The leftmost transistor is generally the only one that fails. There was a suggested sub on the mod section of the basic repair page for this amp.
I warn against using NTE parts. It may be OK for a simple regulator like this but I would not use them.
