[R-390] Re: Pearl tube shields

A final note for those interested in fans: Those ball bearing jobs are also
available in 220V versions, and when run on 110 are **absolutely** silent.
Sure they move much less air but still plenty.

SNIP - As Roy correctly points out, a fan is far more important to dissipate
heat away from the tubes. On the market today are 80cm ball-bearing fans
that are incredibly quiet that can be mounted strategically to dissipate
heat... most useful for those of us that have the unit housed in a cabinet.
My preference would be to mount the receiver in a ventilated rack with both
top and bottom covers OFF.
