AX3 - the new version of ODNF amplifier is in design stage now

Posted by Valery Zaichenko on

Here is the work in progress - new design of ODNF amplifier, based on the great experience of Simpelstark AX2 (also known as V1.3, which is a DIY version of AX2).

AX3 IPS board layout

This design utilizes mostly SMD components, allowing fast, compact layouts with relatively short traces and components underneath the board where required.

Local heatsinks are easily arranged with copper pours right on the board.

Bottom side of the IPS board is a perforated ground plane.

Boards and kits for the current version of Simpelstark (AX2 / V1.3) are available HERE.
