[Shop-talk] Stereo cooling in the garage

[Bob Nogueira]

My 40 year old Realistic stereo in the garage finally died. I replaced it with
a TEAC  unit.   The Realistic unit had a walnut case with the cooling vents
located on the backside. The TEAC unit has the cooling vents on the top of the
case.
I'm worried that with the amount of dust generated in the garage I'll have a
heavy build up of dust inside the case.
 If I place some air filter material over the vents will I be limiting the air
flow enough that the unit overheats.?     Any suggestions  or am I being
paranoid?
Neither unit has a cooling fan,
