In Reply to: RE: CD player with vent holes: bad in the long run? posted by dave789 on April 14, 2017 at 07:22:31
The CD player you are showing is a top loader.
Usually the transport portion of a front loader will be separate from the rest of the unit.
As others have said, those with a tube output stage, will need more ventilation than solid state. To vent or not may be just a design element, or during the design they found a component that was failing due to heat.
I had a preamp that had a component that would fail every six months or so. I had the wood cabinet modified originally to give me easier access to the tubes, but decided to leave the top off. The component never failed again. Once in a while I would take a soft paint brush, and the vacuum to remove the dust.
Follow Ups:
My Ayon has two vent holes each above the two output tubes. I have replaced one of the tubes over its 5 year life and that one failed early. This top loading unit has a particularly tight lid and I've never had occasion to clean the lens or need to. I always keep the lid on except when loading a cd.
