Need help with BAT VK-33


So, a crackle from the right channel of my 4 year old preamp moved to the left channel when I swapped the preamp out cables. When i returned the cables to their original positions,  the right channel became quiet and the left channel became noisy. I can hear the crackle from my listening position. Swapped the tubes and cleaned the pins, but no change. Switched cables, but the problem persists. Is this a job for the BATmen?  The unit is till under warranty. Thanks for your help.

um, i must be missing something here, unless you bought it used from a dealer that also gave you their own warranty, as this is a preamp released in 2007-2008, and is certainly not under any BAT warranty, i would like to know how you could possibly have a warranty on this preamp in 2025?!

sorry, spoke with my tech contact and he said about 2013-2014 release date, so i was wrong, but doesn't change the fact that it still is long out of manufacturer's warranty...so i'm still missing something here....
