They don't come a lot simpler than this.

Imagine you want to use the JLI-2555 microphone capsule or one of the larger, but similarly "without JFET" capsules but you don't want to go to all the trouble of building an amp?

Minerva is a carrier for a JFET such as a 2SK/LSK170 or the 2SK208 JFETs (through hole or SMD) that mounts directly to the rear of most of these capsules and will interface to your PC with just two wires - right into the sound card. SMD components are better factory fitted due to the proximity of vias. Vias should be tented or care taken not to short them on the smaller capsules. The carier specifically converts these capasules in to the standard common source configuration and should not be used for projects that require access to the Source terminal.

Note that screening of the actual capsule may still be required.

Note: this is not an official DIY Perks project but produced for DIY Perks by me as part of the update to an earlier project.
