On the other hand, there is nothing to be gained by setting the voltage to exactly 6.3 volts. Either 6.19 or 6.35 is perfectly OK.
I used a multimeter on the output for exactly 6.3v which actually reads 6.19v
I would assume to much voltage would shorten the life by increased heat?
Its now dead silent while not playing music!! No background hiss/buzz!
