Default Parallel, single-ended Pentode. How?

I have recently completed a prototype single-ended Pentode amplifier using the 807 tube. Since it is still in prototype mode, i was thinking of modifying it to be parallel.

I have no idea on how to run single-ended pentodes in parallel. Can anybody point me in the right direction?
