[QUOTE="sundownz, post: 5779355, member: 549523"] The new case works out quite nicely - we didn't just make it thicker - there are 10mm tall fins under the face of the amp and some extra fins on the sides. The original case really never had any thermal issues to begin with, though - I primarily wanted the new case for future, larger, Class A/B amps. I also did not want to completely change the look of our amps [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] If we do another complete revision I may try to work in some bigger external fins - but I am pretty happy with the performance we get out of the casing now.
