Hello Jeff,
I have gotten very good filters from NMR Services (NMR <info_at_nmr-service.de>,
http://www.nmr-service.de/home.html) for my ssNMR needs (i.e. high power),
which were quite attractively priced and made with the connectors I
specified. I highly recommend getting a quote from them.
Cheers,
Ulli
