What my designs usually have is a power hungry...
I have a 52V transformer that after rect. produces 3.3A at 52V. I wish to use either a LM317 or a LM338 with 2N3055 power transistors.
If you run 2N3055's in parallel you are suppose d to have a resistor like a 0.1Ohm 10W from each emitter so that thermal runaway doesn't take place.Surely the...
