Dear Abby…

-I think my wife is cheating on me. I am a working musician and, as
you would expect, 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 buddy 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 “Sure, you can 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 vintage Marshall JMP
MKII 50W half 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 tubes was not glowing
as bright as the other 3. Is this something I can fix myself or do
need to take it to a technician? 🙂

Thanks
