In the 90's I had a residency in a working men's club in Hull, 3 nights a week in a good band.
Used my Ampeg SVT rig with 810 cab which was placed at the back of the stage, and gave a great
sound. After about 3 years, I joined a pro function band, and so went to the club to take the rig down.
On moving the amp from the cab, I saw that the rear panel (which was perforated metal to protect the
valves) was almost entirely blocked/covered in a yellowy orange substance. This was pre smoking
ban days of course, so the amp's fan had sucked in nicotine heavy air for 3 years, and still never missed a beat.
Dread to think that my lungs had been doing the same too....

Indeed. You only have to think of Roy Castle to have that illustrated pretty clearly.
