cal3713,
I know in the past I have used and preferred the 8ohm taps from other amps with other than Tekton speakers with good results.
I have no experience with the franks and I haven't used a tube amp with my 4ohm DI's other than my Zotl40 and that's not a issue.
You may want to call Israel at Coincident and ask his opinion.
Charles may now too.
Kenny.
