Pioneer SX-1280 Receiver Running On End..?


Is there any detriment to placing a SX-1280 receiver on end (rotated 90 degrees) inside a well ventilated cabinet? It is too wide to place in the normal horizonal position, but not sure if any harm will come by running it on end?

Any advice would be appreciated...

Thank you for the detailed response Elizabeth... This is exactly the kind of technical feedback I am looking for..!

Best,
I agree with Elizabeth. The heatsinks are on the sides and need to have plenty of ventilation. This is a nice old receiver and would sell for enough to purchase something that is newer and smaller(probably not better)that might fit and maybe even run cooler.
Not to mention,all the music will flow to the end that's pointing down!!!!:)
