***********************************Beogram Internal RIAA Pre-Amplifiers **************************************
The Beolover RIAA internal pre-amp is now compatible with all Beogram 4002 and 4004s, and Beogram 4000.
The DC-motor 4002/4004 RIAA is available directly via the Beolover Store. Please, send an email to beolover@gmail.com if you are interested in the AC-motor 4002 or the 4000 versions.

The board has the proper keyboard connector for 4004, i.e. is directly compatible without the need for any modifications. Read more about the performance of the new Beolover RIAA pre-amp in this post.
This shows the same circuit adapted to fit into the Beogram 4000:
It solders directly to the terminal where normally the output cable connects. The board can be switched between RIAA and standard non-amplified phono output. Read more about the installation process here.
