Weren't it only chargers and other consumer products! There are also fake
transistors, IC's and electrolytes that will explode. There was for short a
discussion on an Dutch electronics forum about these fake components. Give
me some time, I'll dig up some photo's

Yeh, If you look at the site of James Cross Vacuum Tubes Inc. There is a
page called 'Hall of Shame', showing the same with tubes [

Actually, there is no background process running on the Arduino; the
I looked at your driver schematics, and checked the transistor datasheet.
The only possible culprit I see from a leakage perspective is the
anode-driver; the NPN device has a 0.1uA Icbo (spec-max), and it could
cause the PNP device to conduct several uA of current for an anode which is
'off'.

Leakage current ? I've seen past designs that use drivers with a
breakdown-voltage-rating lower than the high-voltage supply. I always use
drivers rated at or above the anode supply voltage, even though there are
reasonable arguments for relying
