Counterpoint SA-3000 Preamplifer


My preamplifier now has a his that I don't know where it's coming from.  Does anyone know what might cause this issue.  
Also does the tubes need to be biased? if so, does anyone know how to do it?

Thanks

Counterpoint has a great reputation. Amazing gear. Get her upgraded, , replace caps / tubes. Enjoy another 20 years!
