Danny,
Would it be possible to order the electra tube connectors from you for the MT flat-pack? Ruben would be the one assembling/finishing the speakers so I'd have to ask him to cut new back panels but that's it. He should be getting in touch with you in the near future (if he hasn't already) in order to get woofers/amps and no-rez from you for a pair of super-v that he is going to build for me in the next few months.
Thanks,
David
