Hi!
Just finished my stereo gainclone using two lm4780 chips each running in parallell mode. Before powerup everything semms nice and there is no short circuit and the powersuply works fine delivering 36.7 volts unloaded.
But when I turn the power on I read 0,1 Volts across one channel (out gnd --- out), a bit high but no problem? The other channel reads 3.7 Volts and the chip gets really hot!
Does anybody have an idea of where I sholud start looking? Will try to post some pictures later on...
