Hello,
I would follow Tenor's reluctance and act in accordance with it by not making that particular match if possible. Ralph at Atma-Sphere is one sharp cookie who knows his stuff about tubes and OTL's. He's right and then some.
Also, the Autotransformers will not serve or function as a fused or protected output would in case of a blown or arcing tube. Even if they have isolation properties to them as transformers often do (if designed that way for that purpose), they are for impedance matching, not protection, or at least primarily so. Perhaps a different speaker system would be a good idea. I wish you success and safe and enjoyable listening. Tom
