power transistor for PS. what to uses?
 

Hi everyone I have made a power supply for my rigs

The schematic is the typical regulator with power transistor wrapped around
it for the extra juice.

I need 40 amps continues ..



I tried 4 mj2955 which are rather nice for foot warming in the winter .

I also tried nte-180 which are very good. is there anything better at a
logical price



I would like to keep the number of transistors down to 1 or 2.

Can someone advise my on what to use for power?
