Large Channel Imbalence KEL84

[mudvin]

Hi,

Yes I have swapped the source and the leads as well as the tubes from one side to the other, the issue remains in the Left Channel.

I do have a spare pot and will give it a try, however, as mentioned above it seems to test well.

Regarding the through hole plating, I meant that this particular PCB does not seem to have very good through hole plating, soldering one side the solder does not seem to reliably wick through to the other side like I am used to, and I have done several PCB projects

The other thing I had issues with were those PCB pins which kept wanting to fall out. However I have checked them all and they seem OK.

I will check that alternate pot, then I guess pull the PCB and look for anything out of the ordinary. The issue is that really I have already done that, so I probably need to pull some parts and check or replace them. The issue is which ones.
