Default RIAA preamplifier

Starting with the RIAA Preamplifier (with reduced cabling): LUNDAHL, AMTRANS, MUNDORF, VISHAY, Cornell Dubilier Mica capacitors
The schematics in the attachments.
Working on the power supplies.
Main filter is missing.
... and some Eagle3D/POVRAY symbols (XLR connector, lightpipe LED)

Perhaps, routing the outputs the the rear? and symetrical output?
Central earth and ground near the power supply?
High voltage constraints for the PCB routing (Eagle).

I know its a big board!

See my other ongoing projects:
- C3g Headphone Amplifier,
- 12AU7/IRF610 Hybrid Amplifier,
- 300B Amplifier.
