This is a capacitance multiplier designed by Mark Johnson and Gtose. It was first discussed on the Juma’s Easy Peasy Capacitance Multiplier thread. I have created a dedicated thread for it here to reduce confusion as folks have been posting questions about it on the other thread.
A big thanks to @Mark Johnson , @gtose , and @prasi for making this available to the DIY community.
The layout was done by Prasi and details and Gerbers here:

If @prasi can please insert all of his associated designs in this thread that would be great.
Please continue technical discussions here.

Then, it would be a good thing to add this link: https://www.diyaudio.com/community/...-at-the-capacitance-multiplier-output.389938/
Measurements were done at M.J./Gtose Cap Mx assembled at the breadboard. I recommend to add 22.000 - 47.000 uF capactor at the Cap Mx output for power amplifier supply duties.
