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?

TIA

Cheers.

Hi,

Basically you just wire the valves in parallel.

You'll need to reconsider your PS and OPT as well as RL is halved.

An example using two 2A3s:

CUIFFOLI PSE

Cheers,
