Single stage, single-ended Class A amplifier, 2x15W.

The original article with schematic, and the Return Of Zen article, which was selected to build.

Here is the schematic:

My Return of ZEN amplifier construction notes:

 

	Left The preparation... Right One PCB assembled
	Left Closer look of the assembled PCB Elna Cerafine and Wima caps Right Both PCBs assembled
	Left The heatsinks for Return of ZEN amplifier Size is 227x200mm Right Closer look of heatsink
	Left First test and adjustment of the PCB Right PCB assembled to heatsink
	Left One channel shown, almost ready Right Both channels, before final assembly
	One channel ready
	The ready amplifier (left side is front, right side is back)

 

Chassis designed by myself, and assembled as well.

The whole PCB was designed myself, based on Nelson's original article. The PCB was made at home. PCB properties: 70um Cu FR4 boards.

Components:

- Rhoederstein resistors (1/4)
- Wima capacitors
- Nippon Chemicon capacitors
- DHLabs hook-up wires
- Gold plated RCA connectors
- Wampire binding posts

PSU components:

- Panasonic 10000uF/50V thin body capacitors
- 220W toroid transformer
