Good strategy Nigel. 

Wet slug tantalum- yuk. 

I've opened sealed packaging around new but in extended storage Canberra
NIM 5kV power supplies, had he unit smoke first time hooked power to it.
The rest of them, I just went through and removed all the tantalum
bypass caps before first test.... 

A lot of older nucleonic equipment uses 6V lead-acid batteries, not just
for backup but as a regulator for the main power supply. Removing the
battery and plugging in the mains = instant smoke due to over Voltage.
Basically they are battery operated instruments that happen be float
charging 24/7.
