Hi!
got a problem with a amplifier I built.
the amplifier is the kit from kitsrus nr 106 :http://kitsrus.com/pdf/k106.pdf consisting mainly of the IC: tda 7294
I get sound out of the circuit. BUT after a short while the sound deteriorate and gets very poor and distorted. if I disconnect the power and immediately connect again the sound gets clear but again distorted after a short while.
if I turn up the volume on the input pins it also clears for a short while. why?
anyone got any clues what this might depend on?
I power it from 3st 12v batteries because its used in a portable soundsystem. I use the 2 pins called +34v and -34v but leaves out the middle 0v. I gues 0v is used for some kind of stabilising if using unfiltered DC current?
Would be great with some support! my knowleadge of audio amplifiers are very limited.
thanks! //L
