For use in a headphone amp, i tried a different take on the Gain/BigBloak and it seems to work OK. Is there any interest in further documentation (layout, EAGLE files, ...)?
Excuse the ugly pics...
The output transitors are on the solder side for heatsinking, Of course they could just as well be mounted on the front as usually.
Rounded traces for a true 70s sound :green:
The heatsink/PCB holder i used is a 36 mm piece of 25*15*2mm aluminum (EUR 4/meter)
The complete assebly, ready to be bolted+soldered to a PCB:
The slightly changed schematic:
There is only one bypass cap between V+ and V- because i intend to use it with single supply 48V from a wall wart. The feedabck resistor is included on the board (some space left :green: )
The (not completely up to date) layout:
Any comments welcome :thumb:
