Why would you want to prevent a device from performing
multiple task, especially one it wasn't designed for. An amplifier
sufficing as a bug zapper sounds fun. With the lights turned out
and bugs swarming, you get the aurora borealis effect.

ï Excellent point, Tom. Good engineering practice is to place screen
or perforated sheet metal at the air inlet to keep insects out. For
instance, nothing much larger than a fruit fly can get into a SB-220,
provided that the perf-metal cabinet is in place.
