In one channel I mistakenly used a 2sk1530 instead of a 2sj201 on the minus supply.Switched on and of course got no sound from that channel.Replaced with correct 2sj201 but still getting no sound from this channel.Have I damaged something else in the circuit.
Could someone suggest where to check voltages on various parts of the circuit to see whats wrong.
What can be easier when you have one channel working and one not, you compare the voltages in same spots.
This is what i would do. Check if there is any dc on the output. Check what current flows through output thansistors. Compare voltages between channels and start from there. Read the original thread, lots of people asked already for help, maybe you can find similar problem and the way they resolved it.
Good luck.
