Hi,
I have a Transistor that is partially burned and can read only a portion of the number. 2sk is all and not 100% sure on the k, so not much info. I think the size is a TO-247. See the picture. The board is a voltage regulator and negative 12 to 18 volts approximately would go to the right pin (burned away), then out the center pin to an exciter circuit. There is a fuse of 6 amps on the positive side of circuit that should have prevented this.
I assume the left pin is the base. Also the transistor on left checks ok,
and part on right is a D5LC40 rectifier. I think its bad as it checks 0 resistance both ways from center pin to left pin. Board powers up and may be ok except for above. Would like to try something that may work similar to the original component.
Thanks in advance
