.....larger transformers, wound to provide the same

to kill you. Whether that milliamp gets there depends on 
MANY factors, including the voltage of the source,
how good a contact the entry and exit points for the 
current are, where on your body the entry and exit are.

Any transformer that can power valve gear can kill you.
And, those 'safety cutout' earth balance relays?
They can kill you too. They protect against fire, not
