So my first attempt should be to apply 230 VAC directly, since if it 
fails it needs fixing anyway...

Sorry. Broken logic. Try again.

This is one of the fields which that kind of reasoning DOES NOT APPLY. 
Overvoltage and overcurrent is things you need to know the limits for 
not to cause a mess.

There are other things in which the logic may apply, but again, this is 
not one of those. When having a component in your hand, the same kind of 
range of allowed voltages etc. is not expected since it is expected that 
the box that they go into will handle that as a complete design. If 
every component would have huge overvoltage protection schemes they 
would be bulky and overpriced.

Besides, I have been fairly successful at opening up things and reverse 
them to the level that I know what levels I can use.

Cheers,
Magnus
