[Boatanchors] Hello again

[Richard Knoppow]

    Many boatanchors generate a lot of heat so its really not a 
good idea to stack them. Can be stacked on shelves that allow 
ventilation. Now, if you are going to run one thing at a time its 
not so bad _provided_ there is enough ventilation. If you plug 
all the vents in something its going to heat up even if the 
things on top of it are not turned on.
    Something else is that its not a good idea to have a 
loudspeaker on top of a radio because the vibration will couple 
and cause feedback. Nearly all receivers are microphonic to some 
degree or other.

I figured I would get some opinions on this and wonder if hams do stack these old radio on top of each other?thanks again!73Rich
