Project: ne5532 preamp

This is a preamp I recently designed.

For ease of construction, this project is based on dual opamps, and will accommodate several different dual opamps.

The following can be used without modification.




+ many others.

The topology used is: input buffer -> vol control -> gain stage -> output buffer

The gain is quite low, as it was designed to be used with digital sources, but the gain can be usefully increased if required.

Below is a 3d model of the board - I ordered my boards from JLPCB and have build a couple of them and they work well.

This version is all DC coupled.

See this link for the alternative single opamp based version.
