Forgot to update. I ended up with this set up and I'm loving it:
Technics SL-1200 MK5
Audio Technica VM540MV
White Steel Headshell
Technics RGS0008 Mat (292x2.8mm, 298g)
Cherry Audio Acrylic Mat (295x3mm, 237g)
Quality Electronics White Faceplate
Reloop Dust Cover
Femeli 304g Short Weight
Muffsy Phono Preamp PP-4 Kit using Schiit 16VAC/AC 500mA adapter.
I first bought the recommended Jameco Reliapro ADU160100Z5401 on his page, but the transformer was humming loudly and it was HUGE. I returned it and got the Schiit he also recommended. It's still dead silent after a few months. The Muffsy wasn't too hard to build and was my first time soldering a board from scratch. Stripping the cables and getting them the right size was the hardest part. As you might see, I tried to follow the instructions exactly, but they seemed too long in the end. They did work but just had to bend the cables a little bit. There was extra cable left over so if you mess up a cable it's ok. The Muffsy sounds great and I love the minimalist boxes it's made to go in. Although I don't want an LED shining out the front plate, I've left it on a few times so I may try to add that at some point.
