I posted this in a different section earlier, but got no responses. Hope crossposting is ok.
I have an old Telefunken Magnetophon 97 Tape machine. The wheels dont turn, but the tubes have been testing fine. I'm trying to salvage the mic pres out of it, make something rack mountable. Any documentation i've been able to find has been in German

Is this dumb? Should I just steal the tubes and build something from scratch? Theres a pair each of EF86, ECC81, and EL95. And one busted EM84 catseye tube. It would be really rad to use that as a level meter, if i can find a working one.
I can recognize most of the stuff on the circuit diagram, except for what looks like a dotted circle with a T coming out of it. Maybe a ground? You can see em around K or M.
