I was having microphonics issues in a Peavey Encore 65 guitar amp (especially at high volume) and since my tube tester can't identify that kind of issue I replaced two 12AX7s and one 12AT7 with these JJ ECC83s and ECC81. Problem solved and, it may just be me but, I think it sounds better too. Good price too by the way.
