Useful information to build your own audio pre-amp and power amp based on my own developed circuits.
my own realization of the amplifier
Unpopulated PCB (layout done by Project16 based on original layout of Alex) with BOM can be obtained from designer upon request for diy personal use ONLY.
After doing more elaborate circuits, I have decided to get back to basic circuits and re-start from there. F5 amplifier I a good example of using only 4 transistors in symmetric configuration to obtain good sound results for such a simple amp in parts count. Simple circuits allow generally to get the sense of a more natural 3D sound. The USSA series is an attempt to preserve a natural tonal balance over the whole audio frequency band
From my avatar on audio forum some may think I am living in the jungle but unfortunately that is not the case...
Also, " Fabaudio" is different from "Fab Audio" the loudspeaker Canadian manufacturer.
