Cigarette Smoke Harm Solid State Unit ?

I once bought a used pre amp that also heavily reaked as if the original owner was a chain smoker. I now always ask the
environment that a unit was kept in to try to reduce the
chance of buying something used like that again. I did manage to sell that pre amp a while later and it never lost
that smell especially when it heated up from use. I think
this is also very improtant when buying any loudspeakers due
to that they usualy have fabric grills that hold the smell.
