Hi,
Attached is a circuit where I am trying to get 24V 1A output, the zener diodes are ment to put 36V to the base of the transister and 12V to the common of the voltage regulator. I am currently getting 39V to the base of the transister and 15.4V to the common of the regulator. I have tried puttin a resistor before the zeners and got the correct voltages but the final output current was then limited to 250ma. Basically I need the zeners to drop the correct voltages without limiting the current to below 1A.
