Just to be clear, we shouldn't worry about ordering the SAMTEC connectors until someone at JLab signs off on the NPS chassis connectors boards?</div>

That's fine with me, just wanted to make sure it wasn't going to be a problem if we couldn't order them before the end of this fiscal year.</div>

I believe that will push the 'NPS side' of the NPS HV connector issue<br>
