Hey folks,
I am repairing a power supply and am reasonably sure I see the problem, but before I replace any parts, I'd like some opinions. I am going to post a simplified schem. of an NTE 2310 npn high V high speed switch in between two transformers. As I read it, T1 induces an AC signal at Xhz through the secondary to the base of the transistor, which switches at Xhz, producing elevated alternating DC through the primary of T2, which induces the same into T2 secondary. I am reading approx 320VDC across the E-C pins of the transisor with a VM, shouldn't I be reading AC? I am also reading voltage on both legs of T2 primary with respect to ground, but no voltage drop across the primary, and no voltage is induced into the T2 secondary. I am suspect of the transistor. Any opinions?
