Several people have been in touch lately with questions on how to modify the PCB into something it isn't right now. Popular requests are balanced inputs and/or balanced outputs, and DC servo on the outputs.

The instructions give you three alternatives for powering the Muffsy Phono Kits. Here's another one:

This step-down power module is available on Tindie, and can provide up to two amperes of power. Use two of them and connect a 15V DC power supply at VIN/GND as shown in the picture above, and you will...

Hot on the heals of the official Muffsy PCB, here comes another option.

Over at theslowdiyer's blog, you can now find the project files for the Muffsy Clone.

Yngve from Norway has built a total of five Muffsy Phono Preamps by now, but this has to be his coolest project ever. When he bought a Dual 1225, he decided to give it an integrated phono stage, using the Muffsy.

The Dual 1225 was opened, the drill was brought out, and the Muffsy placement was decide...

In Copenhagen, just across The Bridge from me, lives slowdiyer. He has designed the Muffsy Clone, his own version of the Muffsy that suits his needs exactly.

It is a mono version with single instead of dual op amps, which lets you use op amps like LME49710, LT1063, LT1028, AD797, OPA627 and more.  B...

When you're going through the trouble of building something awesome, you should at least expect to be able to change it any way you'd like. Right?

Well get ready. The Muffsy Phono Preamp and Power Supply can be modified to suit your exact needs. Other gain levels? Check, Audiophile resistors, new ope...
