Hi Mike.

It is not advisable to connect different voltage windings in paralell. The 
reason is that the higher voltage neons would feed the difference into the
lower voltage neons. If it were lower voltage transformers they would 
probably survive but at this voltage level internal arcing (or overheating) 
is likely to destroy one or more of them.
You should only paralell transformers if they have the same voltage rating,
then you would get the gain in current. If your three transformers had the 
same voltage rating and connected them in paralell you would virtually end 
up with "one" transformer of (n Volts / 90mA)

Hope that clear it up for you.
