There are several ways to make your own Muffsy Phono Preamp, but the power supply has been missing. Until now. Below are both gerbers and PDFs that allows you to order or etch your own power supply boards.

There are a couple of differences between this board and the power supply kit:

• The board is single layer (bottom) with ground fill
• The AUX power has been left out

• The Gerbers are in 274X-format, view them in Gerbv to see how the PCB will look like
• Order as two layers to get through-hole soldering pads, and solder mask on both sides
• There is very little copper that needs to be etched away if you're etching yourself
• The PDFs have the bottom (copper) layer and the top (silk screen) layer, paper size is A4
  

• The bottom copper layer is oriented so that it can be toner transferred directly to the PCB

We've seen some revisions of the Muffsy Phono Preamp, from green to red,  through blue and finally the black PP-3. Now get ready for a new one, only this time you can't buy it from here.

The question of a more generic circuit board that will accept other components than the ones included in the kit pops up now and then. Although there is nothing stopping you from designing a circuit board from the schematics, that might not always be a viable alternative.

As the Muffsy is based on the Audiokarma CNC phono stage, this is my way of giving something back. You will find a PDF for etching your own board and Gerbers for ordering it further down.

Here's some information about the board:

• The board is single layer (bottom) with ground fill
  
• There's space for larger capacitors (RIAA: 5/10 mm, Output: 10/15 mm pin spacing)
  
• There's space for wider resistors
  
• The width is 84 mm, it will still fit in a B0905 cabinet
  
• It has the standard Muffsy values for input impedance and RIAA equalization, all within the E24-series
  
• It has variable gain
  
• There's space for input capacitors
  
• Input, output and power in has 5 mm pin spacing for terminal blocks
  
• The Gerbers are in 274X-format, view them in Gerbv to see how the PCB will look like
  
• Order as two layers to get through-hole, and solder mask on both sides
• There is very little copper that needs to be etched away if you're etching yourself
• The PDFs have the bottom (copper) layer and the top (silk screen) layer, paper size is A4
  
• The bottom copper layer is oriented so that it can be toner transferred directly to the PCB
