I made a 30 volt power supply with the LM388k and a 24vac 12 amp transformer to eventually use on a 4 x 100 watt Class D amp.
The circuit initailly put out only 20 volts until the resistor connectiong the input voltage to the input of the LM388k and the base of the 2N3907 opened. Now the power supply puts out 30 volts @ 68 watts. All the heat is across the 2 resisitor and everything else is cool.
My question; is this circuit an accident or a usable design?
