Got some files of Goldmund-style Preamp design, based on Mimesis 27 PreAmplifier.
I have transformed the file to Altium format, also ASCI or so.
The Mimesis 27 uses A20 modules as front-end amplification, but in this way, additional A2 PCBs are required,
so the design shown here cancels the modules, directly place the components on mainboard, which I think is more friendly for DIYers, unless you're pursuing 1:1 Clone.
As for power supply, the filtering capacitors adopt axial design, very iconic for this type of Preamp; it's actually capacitance multiplier, 45-0-45 VAC Input.
The Iconic blue-shell axial capacitors: Vishay BC (Philips) 470uF/63V, 1000uF/63V, 021 Long Life series.
Rifa PEG long life series is also my favorites too.
Haven't decided how and what to share, just started the soldering work.

Feedback capacitor: Nichicon MUSES?
The PCB produced on the basis of file.
