Modding two of these to push-pull will be pretty difficult. Why not go with a push-pull 845 amp? Also, you might be able to find a winder here in the US who can make you an appropriate transformer to parallel a bunch of 300B's. Doc B. has been working on paralleling multiple 300B amplifiers together to drive some inefficient small woofers, and it's been working out well, but we haven't bothered measuring what will happen at the higher frequencies.
Honestly, you need to get from 84db to around 103db, so say 20db for some error margin. That means 100 watts of output. Push-pull 845 will do it, but 100 watt single ended amplifiers are expensive and uncommon. (Goldend tube SE-100?)
