PAS line mod PCB

Someone have experience with Classic valves design PCB. Their PAS line mod PCB sound interesting even if i an not entusiast about it's hybrid design.

I have plenty of nice single 12AX7 12AU7 (amperex and early 1950's RCA black plates etc...) and i want to try them.

The Cascades tubes Universal 4S preamp seems interesting too.
