Don,

Thanks for the reply..

The plastic tab safety factor was obvious but, of course, I was wondering if there was an 
improvement in the upper frequency efficiency.....

I will definitely keep tha in mind... on the surface it looks like a simple swap --- the thing to 
decide is if there is a real noticeable performance improvement...

Thanks again...
