SK99


The SK99 is a discrete Op-Amp that is pin compatible with the API* 2520. It is a low noise, high performance DOA that has been specially developed for audio applications.

The SK99 will give its best noise performance with low impedance source, like low ratio input transformers (1:1 to 1:5) or transformerless input.

Highlights

  • Pin compatible with API 2520 and “99” DOA's
  • For input transformers with a ratio of 1:1 to 1:5
  • 100% Class A with RL ≥ 600 Ω
  • Wide frequency range
  • Low noise, high speed, high gain
  • Very good stability
  • Wide supply voltage range from +/-15V to +/-24V
  • Rich quiescent current
  • Short circuit protected output
  • Available assembled or as a full kit (everything included)

What's in the kit?

Everything!

You bring the solder (use good quality solder, 1mm diameter max).

Difficulty level

The SK99 kit is not a kit for beginners because of the high density of components. It is recommended to people with some soldering experience.

Product Options

Assembled Product: If you prefer not to DIY, choose an Assembled product. It comes fully assembled, ready to use.
