I built Aleph5 with Mark Finnis PCB project. (for his aleph4) In the power supply I used "Pi" filter with two 1,8mH aerial coils and 120 000uF total capacitors ( 12x10 000uF) custom made toroidal transformer 600W / 2x27V secondary voltages metal film 0,6W Yageo resistors (and 4W MOX ) ZTX450 (instead of MPSA) and IRFP240`s
all the parts matched.

Enclosure is made with aluminum (5mm and 2 mm) - using only hand tools - it was hard work !

Bride Of Zen - similar to my aleph 5 . I use no input selector cause I
don't need this and that's all.

Oh , I forgot : the sound - it's really superb !

clear with deep bass ..... excellent dynamic ...
