Hi Ryan,
Apparently, some neon sign shops use many paralleled NST for cheap
bombarders. I don't "know" of any problems but they may be something we
don't know. O:-|
I would carefully check each one to be sure they are all working. If one
is shorting, the high current being dumped into a bad one could do odd
things. If you can't find a problem you may try removing them one at a
time to see if one is causing the problem. Beyond that, you may be seeing
something we are not aware of...
Cheers,
Terry
