The EF86 is a pentode, so yes, you can find (2) with close to same specs.
There are plenty of good NOS still out there that will probably do you better than a JJ. More expensive yes..but why not use the best?
As far as the "Oh..they're all microphonic BS" don't believe it. They got a bad rap because they were used in apps that applied too much voltage/current and made them microphonic. Vox AC-4/15 is an example. if good design parameters are adhered to, you won't have a problem.
