Hi
I have a Krell KAV 300i, it seems to be working ok with single ended inputs but there is a loud pop when the balanced inputs are selected, there is also a little humm and some crackle noises when the balanced inputs are selected.
Also some popping noise when the digital volume control is adjusted, thats with any input selected.
I suspect the fault is caused by an excessive dc offset in the preamplifier section, perhaps powersupply, or servo related.
Problem is getting access to the lower board.
Anyone know if its possible to remove the upper input selector board without removing the whole amplifier from the case?
Thanks.

Hi, I know this post is quite old but I wonder if you ever got this problem solved. I have one that I bought mail-functioning. I did a full recap but the original problem still exists. I have a fluctuating Dc offset at the output. I am thinking the servo might be causing the problem.
Thanks
Thanks
