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.
NE5532
OPA2134
LM4562
+ 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.
