I have nearly all Zimo as per my post earlier but do have a couple of TCs and I have found they don't preform as well as the Zimo's, although I have left the caps in place.
My 511 has only been used with caps in place so I don't know how the TC's would perform with them removed.
I am more than happy to keep using Zimo's though.
No interference on my Plasma at all
Something to do with it not being affected by RF anyway
