Hagerman Bugle MM Phono Preamp

00:50:40

The Bugle (and its variants) is a solid-state phono preamp from Hagerman Audio Labs (formerly Hagerman Technology). It’s often sold either as a fully assembled unit or as a DIY kit. It’s popular among vinyl enthusiasts for being high value, flexible, and very transparent in sound.  

*Components may differ from the original values since i adjusted to commercial values.

This preamp is evaluated using an inverse equalization network also designed by Jim Hagerman, which is connected as a load to the preamplifier. Looking at the frequency response curve (green curve), one can notice a fairly flat response, as can the orange curve, which is 20 dB lower than the green one.

How do you make the bode diagram ?

You have asked this question before, Spiralvert, and I have answered you. Let me remind you: If the circuit has an AC source, no square wave sources, and no logic trains, there will appear a triangle button marked “f”. Pressing this will run the Bode Plot simulation

The button will appear between the “Run Transient” and “Save Circuit” buttons
