About the PassDIY Aleph 60
The PassDIY Aleph 60 is a DIY monoblock power amplifier project based on Nelson Pass's original Aleph 60 single-ended Class A design, delivering approximately 60 watts of Class A power into 8 ohms per channel. Like the commercial Aleph models, it uses Pass's single-ended Class A current-source topology, which optimizes performance across varying loudspeaker impedances. The original Aleph 60 circuit is notable for having no user-adjustable bias or DC offset trimmers, with operating points set by fixed component values for long-term stability. DIY implementations follow the published Aleph 60 schematic, allowing builders to choose chassis and components to suit individual preferences.
