I keep my Marantz receiver covered with a cotton cloth on top and sides after giving enough time to cool off and if it is a dedicated room, keep doors and windows closed as much as possible to prevent dust. I live in a developing extension area where house construction is the norm.I recently bought Marantz PM5005. It has a lot of big air vents on wide are of top of the unit. I have never any equipment with such a wide air vents. Now my worry is how to prevent it from dust enter and deposited on PCB? How do you guys manage?

Moisture shouldn't be a problem as the Receiver gets warm enough when in use. When compared to lenses this is not a big deal. We use humidifier and baking in sun to keep our lenses from accumulating fungus and moisture.Dust is no villian compared to moisture and power fluctuations. I never saw any amp dead due to dust.
From where I come(kerala) , in monsoon season, the moisture levels are very high that, wood on speakers get fungus, paper cones sometimes in some cases also get fungus. Technicians at our place always says that moisture can cause condensex droplets on legs or small microcontrollers causing them to short. In this case before the warming up happens damage will be done. Also certain inductors corrode exposed to moisture. I am not sure if they are right altogether ,but after having complaints with denon , onkyo receivers (always with small processors or components like that ) at kerala and never at Chennai where I previously worked I kind of believe them. Also, joints on boards can corrode and can there by altering the circuit leading to damage. I heard the same story from more than one technician.Moisture shouldn't be a problem as the Receiver gets warm enough when in use. When compared to lenses this is not a big deal.

In summer a lot of dust get settled. In monsoon when humidity increases the settled dust gets moisturised. It will cause harm, right?Dust is no villian compared to moisture and power fluctuations. I never saw any amp dead due to dust.

As you rightly mentioned, moisture has been a real headache. If your AV room has an air conditioner, use dehumidifier once a month.

Old stereo amps with mechanical switches seems alright in this case. Not 100 percent sure, as I am no expert with working on boards.
