5058G Germanium OpAmp [Assembled]

Description:

Please note: Assembled OpAmps always come with 0.5in / 12.7mm API length pins.

These should still easily fit all devices.

We developed a new high gain topology that is not based on anything available so far, to bring you a fresh and new flavor. For that, we spent countless hours developing, listening and comparing components to find the perfect match.

The 5058G is implemented with matched transistors housed in the same package for superior matching and reproducibility throughout.
The design deviates from the standard output transistor packages to a single chip to provide superior thermal coupling between the transistors and the biasing diodes.

The 5058G utilizes 18 transistors with most being a current mirror or load to improve stability and usability. These transistors, except the germaniums, are all premounted on a beautiful black and gold PCB and do not require additional soldering. The kit only requires the soldering of resistors, capacitors and diodes and the matched germanium pair, which makes it easier to build.

Sound and Versions:

The original version is very defined and clean, yet punchy, with that added warm vintage vibe rounding off the edges.

The enhanced version beautifully focuses and enhances all transients without sounding harsh. It's a tad less mid forward than the original version but adds another layer of punch and the vintage vibe is a bit more subtle.
