I also fixed an unexpected bridge rectifier problem in the other 15V section. Some more electrolytic capacitors tested and replaced. Adjusting the feedback PID to prevent unwanted oscillations. A leaking, shorting and exploding paper capacitor in an interference filter. Some oscilloscope measurements in the thyristor controlled rectifier section that pre-regulates the voltage.
