Hello all
My AI500 has a small left channel crackle.
Slight and very random, not continuous.
I have tried valves out tests.
centre pre-valve out gives louder crackle.
left channel out the crackle disappears
volume control doesn't affect it
source selector doesn't affect it
with driver valves out it is still there
I have swapped driver valves over and it stays in the left
I have changed all the small valves and it is still there
I have checked loose, broken missing solder and damaged wires
It is mainly noticeable at switch on and after a while it settles and comes back when hot.
Do any of you clever valve people have any ideas that I have not tried
thank you all
