Here is a blast from the past - a Silicon Chip phono stage (I have two other kits from 2006). Nice part is you can switch between three different EQ stages if you really wanted. Comes with a PCB and all the parts required. It uses the LM833 OPAMP but it can be swapped out for a OPA2134.
Apart from leaving a few parts off and installing the wrong cap in the EQ stage and having to play with the gain, all went well. The original idea was to have variable gain but a $2 pot in the gain stage seemed a bad idea. It is a two stage preamp where Mimic is a single stage.Solid core hook-up wire was used in a Hammond Al enclosure and WBT silver based solder. Original to be powered by an AC wall wart now running on batteries.
Sound is bright and immediate where my DIY Mimic is more about tone this one is about detail.

Very nice DIY phono.
The Graham Slee Era Gold V was one of the better sounding MM phono preamps that I have owned. It also used a couple op-amps, a pair of Analog Devices AD817 parts made for very high speed signals including image acquisition and video. Simple layout, small parts count, but wonderful sounding.
I ran mine off two 12VDC batteries in series:
Looks good. My main MM stage is a DIY Radi0Kit tube stage with high end parts. This one is good for a real change.
