After opening the set I went straight to check on the safety components:
I found the surge limiter Resistor (dropper) open circuit but the fuse ok.
I replaced the dropper and powered on but it blow again instantly, I wish I had used the series bulb but it was too late.
I replaced the dropper again and used the series bulb and I notice d the bulb was lighting with lots of brightness indicating a heavy short. I measured the voltage across the man capacitor and found around 65 volts.
