[QUOTE="tangmonster, post: 179379, member: 1581"] Remember to take into account the extra heatsinks needed. For the old F5 with 25V rails and 1.3Amp bias per rail you get 65W constant power put into heat. For v1 you have 1 amp over each device and that calculates toe 32V rails that calculates to 128W constant power converted to heat per channel. You will need to start using a fanned heatsink a black anodized 200 x 250 x 40mm heatsink is around 0.3C/W , this means nearly 40C above room. 65C is a bit too high. FYi , this is Krell KSA50 territory , believe me , you need active cooling. [/QUOTE]
