kier Posted July 6, 2012 Report Share Posted July 6, 2012 i put this cct together to suit my needs of a) delayed turn on of the relay; b)fast turn off when amp is switched off; c)dc dectection; d)powered from the amps main rails of around +/-57V.the front part does the dc dectection, and i joined it up to another cct i had come across, for the delayed turn on and fast turn off.it works most of the time, but now and then the relay drops out after a few minutes from switch on and then after 5-10 mins slowly powers up again; another time the relay failed to energise at all after the switch on.
