Hi all，   STTH110，the role of the diode in the two-tube forward circuit is the demagnetization of the transformer, which is found to burst in use.   The diode is exploded in the middle, pictured below:    The question is how did the diode break? The ...

Hello, I am using ‘STTH110’ as a power supply for magnetic reset of two-tube forward circuit. We are using ‘STTH110’ as a power supply for magnetic reset of two-tube positive excitation circuit, and there are diode breakage and short-circuit failures...
