Help with Vintage B&K Power/Pre Amps


I have a ST2140 power amp and a PRO 10MC Sonata Series preamp... thought I had trouble with one of my tweeters (right speaker sounding overly bright to the point of listening fatigue)... a friend brought over a pair of B&W monitors and after plugging them in, the right speaker had overly bright highs as well... anyone have any idea what might be causing this... do I need to send the 2140 into B&K to diagnose, or maybe the PRO 10MC, or both... any suggestions appreciated... this journey down the vintage equipment road can be challenging... thanks in advance.

I recently attempted to contact B&K/ATI via telephone and email regarding an older model pre pro I was experiencing problems with.

They never bothered to return my phone calls or email.
