Dear Abby. I think my wife is cheating on me. I am a working musician and as you would expect, I travel a lot. I have been noticing strange things happening when I get home. Her mobile phone rings and she steps outside to answer it or she says, "I'll call you back later". When I ask her who called she gets evasive. Sometimes she goes out with friends but comes home late, getting dropped off around the corner and walking the rest of the way. I once picked up the extension while she was on the phone and she got very angry. A mate of mine plays guitar in a band. He told me that my wife and some guy have been to his gigs.

He wanted to borrow my guitar amp. That's when I got the idea to find out for myself what was really happening. I said that he could use my amp but I want to hide behind it at the gig and see if she comes into the venue and who she comes in with. He agreed. Saturday night came and I slipped behind my Marshall stack to get a good view. I could feel the heat coming off the back of the amp.

It was at that moment, crouching down behind the amp, that I noticed that one of the power stage valves wasn't glowing as brightly as the other three. Is this something I can fix myself, or do I need to take it to a technician? Thanks Very Concerned.
