The circuit can be delayed and led excitation speaker dc protection circuit.A current of approx. 70mA. The appropriate value for the high voltages are selectable Rs resistance.

For example: Amplifier 2x24Vac with the feed from the same place, we can get this circuit.Aim will be about how to find the value and power of direncimizin 34Vdc.

Rs = (34-17)/0.07 WRs = (34-17) x 0.07
Rs = 243 ohm WRs = 1.2 W

547 = BC547, 139 = BD139

250 k potentiometer with approximately 1-9 sec delay setting. Operation of the circuit in addition to certain clear min. 0.8 V is active.
