Hi Mike, The main system isn't running anyway.

Their current state is a reflection of a previous plan using a three sphere stack with a Manger driver from Germany in the middle smaller sphere running from 150Hz @ 1st order with the two bass spheres tried at 3rd and 1st for LPass.

But the idea of a 1st HP & 3rd LP crossover works quite well with dipole planars, too.

I will go with both the LEAKs in Pentode. I should then have about 40 watts pc into the 63s, and with the 150Hz high pass that should be just enough power. We will just add a 4th PSU cap to the one with just three.

We aren't using 12AX7s anywhere in the LEAKs. The shared input valve is a 6DJ8 and the drivers are 6CG7s with a FET CCS. See URL below my signature block.
