In Reply to: RE: Removing top cover... posted by Jonesy on September 15, 2020 at 12:08:15
Even if the top cover is the heat sink, does it not also act to keep
heat inside the case? And if this is the situation, would not removing the
top cover/heat sink allow more heat to escape, thus obviating the need
for additional cooling? Or am I missing something?
Whether or not you can observe a thing depends upon the theory you use. It is the theory which decides what can be observed. - Albert Einstein
Follow Ups:
Air alone would not dissipate the high heat from the output transistors in this class "A" design. You need heatsinks.
The transistors are mounted on a (aluminum?) bar. The bar is coupled to the cover with thermal paste. The cover is ribbed to work as a large heatsink.
If the cover is hot it is working properly.
Remove the cover, the transistors will overheat.
Musical Fidelity did this interesting design to maintain a modern slim look.The alternative would be to have a taller cover drilled for ventilation. And then large internal heatsinks for the transistors.
Hope this makes sense.
Cheers!

for using the top cover as a heat sink. I think.
I'm not an engineer, and my understanding of physics is rather limited
(to say the least!), so I defer to those who are more knowledgeable in
these matters, such as yourself.

I'm no technical expert either. Sometimes I feel comfortable commenting only because of trial and error experiences.
In this instance, besides my own experiences with heat sinks, I related to the many super (gaming) computers my two sons have built over the years with heatsinks, fans, and water cooling systems. In their case it was for processor chips vs output transistors.
So much crossover technology out there!
Cheers!
