Dear friends
Iam interested to build a phono preamp(mm) with noise filters specifically for 78 rpm shellac records .I need guidance to source for RIAA circuit ,and noise filters circuit to remove surface noise, hiss,rumble and equaliazation above 6khz for shellac records. On googling i did find some circuit diagrams but wondering how to interlace them and is any transformer needed for the necessary amplication at the output stage.
My end result of the preamp is to signal out clear music to a good amplifier.Which is the best signal to noise ratio and how do i achieve it?
Kindly guide me.
Regards
