Amp Camp Amp Redux
Amp Camp Amp Redux
The original Amp Camp Amp circuit (V1.6) by Nelson Pass in a unique form factor optimized for easy assembly and reduced cost.
This kit contains all components, hardware, and power supplies needed to build two single ended class-A monoblock amplifiers.
- 8 watts into 8 ohms
- 10 dB gain
- 10KΩ input impedance
- Current stock uses JEFTs and MOSFETs sourced from Nelson Pass
6L6 at diyAudio has written detailed instructions to guide builders through the process.
