Don; The 2SC3310 is shown as a replacement, also NTE2337. Has the same ratings on characteristics. 500v, 5A, 30 W, NPN Marvin Hardin Martronics Armuchee, Ga.

It is good for a month or so but shorts again, I checked all resistors diodes and replaced many caps, all good. I have heard that there is a better transistor to use than C4418 but do not remember what it is, does anyone know? Any help is appreciated.
