I made a regulated power suply with the "classic lm723" .In the original circuit the courent source was a 2n3055 transistor. I had a spare MJ3000 and i used this instead of 2N3055.
The problem is that in idle mode the maximum voltage is 6.5 V instead of 12V. I checked the Out pin of the 723 and the voltage is changing according with the Vref variation on the non inverting input on pin no. 5 on the LM.
I will attach the circuit here.
Please help me.
Thank you!
