Hello all,
*
I want to build a 50v power supply for 2x MRF157. I need about 20-30amp. Allt he components are here availaible, trafo. capacitors, 50a bridge rectifier etc..
*
I know the easiest way is to use a switched PS, i have some of it, 50amp from HP servers. But i want to build an "analog" version
*
Searching on the internet i found this design using the old LM723.

Do you have another idea with using a more modern components but with current protection etc. please let me know!
Tnx and 73,
