Hi - I have a Mesa Boogie DC-5 combo that I bought in the mid 90s. When I change channels either from the foot switch or the switch on the amp there is a loud pop sound from the speaker. I tipped the amp forward and watched the tubes and one of the power tubes slightly flickers when I change channels. Is this likely the culprit? I don't have any other noises (i.e., hissing, humming, static, etc.), only the pop sound when changing channels. The power tubes were changed once back in the 90s when I was part of a band, but I remember that "pop" sound happening at the time I quit playing out. It was really prominent through the PA. All these years later, I'd like to finally fix it and restore my amp. Please share any thoughts or advice. I know I can take it in, but if it's likely a tube problem versus something with the channel switch (remind you, it's both from foot switch and switch on face of amp), I can save myself the expense and just replace tubes. Thanks!!!
