Is it possible to use a 1 amp lm317 pcb with current limiting to drive 2N3055 and keep the current limiting ability? b to output lm317 pcb + c to + on bridge e to 0.1 ohm and add as much as needed, in this case 4 x 2N3055. I know this works for a variable psu I already build one. The pcb did not have current limiting only voltage regulation wich works perfect. But this time I would like the ability to limit current as well..
