Default Does anybody know of a single opamp/feedback loop eq preamp for 78's?

The title kind of says it all. What I am looking for is a schematic for a 78 rpm single opamp stage (i.e. feedback loop) preamp equalization circuit. I have looked and looked but cannot find one. I guess they are not common for various reasons. I am only really interested in 1 eq curve, the BSI curve that was used post 1953.
The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts. Bertrand Russell
