PC board design for PSE amp

Hi,

I want to design a PCB for my PSE amp. Simple circuit, one paralleled driver tube with CCS connected to two paralleled pentodes. I've done a few PCBs in the way past for digital I/O and such but never audio.

Can some of you folks offer advice for what my concerns should be related to signal and power routing?

Is it best to plan on hard wiring the filaments and keep them off the board?

Is it best to have a separate board for the power supply?

Maybe it is best to make them one channel boards with their own power supply?

Any help is greatly appreciated.

Scott

I meant to mention that the design uses a SS power supply.
