Oscillation (or just getting very hot)
I have just finished a Parallel kit using Brian GT's boards. To paralell the amp I simply placed two .5 ohm resisters in paralell on the output of each board resulting in a .25 ohm series impedence for each chip. With no input the amp stays cool. When I add a small signal the amp quickly heats up.
I have used a star ground for the power.
