EF86 or better still EF184 in pentode form giving around x 400 gain followed by a cathode follower then wrap the feedback around the Baxandall network.

There are many ways of making a pre amp and hundreds of schematics on the web.

There will be plenty of designs from back in the day which you could just remove the phono section from. Beware of some old designs being intended to drive >100K load though! Keep the cathode follower.

If you didn't want tone controls I'd have linked to a design of my own intended for easy DIY build.
