Amp trouble

[kc-silo]

Hi I'm wondering if anyone can help? Today I turned my amp on (Peavey JSX) and when I turn the standby on i get a static noise for a few seconds and I seem to have lost some of the low end if anyone knows what could make this happen any advice would help. THANKS

9 out of 10 times it's a tube issue. If you're concerned, take it to a tech.
