Hi, can i use 26v-0-26v ac for a pair of parallel lm3886 with 6 ohm speakers? Or, 25v-0-25 ac is the border for this configuration for the healty of the amp? I mean does it matter 1v ac difference in way of putput power and heat dissipation? Thanks
account main line's voltage fluctuations and you may kill the ic.
if that is the xformer you have you can anytime add diodes after the rectifier bridge to drop the voltage a bit , if needed.
