Studio Tube Preamp

OK, please forgive my poor knowledge. That design does need separate windings.
Then I've to connect one leg (or CT) of V2 heaters' supply straight to V2A cathode? Correct?
Many thanks!

Yes.

Ok, I made the mods and h-k voltage is 75V. Many thanks for your help
Separate heaters' supply makes this preamp someway complex but I don't know other similar DIY projects available online so it's a choice anyway.
Just for the records, Nachbaur's projects pages are down since a few days.
Thanks again to you problem solvers!

Hello,
Fred had mentioned on his webpage gerber files for the phono preamp. Since Fred has not been with us for quite some time, does anyone have the gerber files for the preamp?
Just a shot in the dark.....

Thanks, Phil
