Aleph 5 - work in progress
Thought it was about time I put some photos of my project on record. Apologies for poor quality, I used the camera on my mobile.
I am now at the stage of having most of the required parts but need a few quiet days to put it together. The box you see is one of two monoblock A5's. These will contain half of the total capacitance used, 104000uF per rail (416000uF total), and the signal electronics. The PSU cases, yet to be designed, will hold a 625VA trafo each and the remaining capacitance along with air-cored 3.3mH inductors. I may cheat with the PSU case and get something pre-made as they are less likely to be on display. |

Top plate is an aluminium channel 150mm wide bolted into the directly heatsinks, front back and underside are aluminium sheet. Makes for a simple but sturdy construction. The aim internally will be to keep all interconnections as short as possible.
Thanks to diyaudio for getting me this far. Special thanks to Nelson Pass for the circuit and his forum input, Harvardian for helping to obtain parts, Brian GT for the excellent PCB from the group purchase last year. Cheers Paul |

Connections
Chris, I have some Neutrik locking mains connectors. The cable will probably be one of the TNT audio braided designs but I remain open to other ideas.

Hi I had the same question some time ago: external trafoos, how?
I still wonder what is best, to put the trafoos+rectifiers outside or only the trafoos. Are you using Neurtrik Powercons?? btw my enclosure and PS is for 2 channels  If I would start over again, I would probalbly also go for mono blocks
