active system, first pictures

[aaronboumans]

first pictures of my new active system
2x21w8555-01 with Aleph 5
12m4631g00 revelator with A3
d9505/990000 revelator with a3

A5(mono) contains two seperate toroids (300VA) for each voltage rail, two bridges, 2x47000uF, 2.2mh(0,47R), 2x47000uF+12x4700uF
A3(mono) contains 470VA, 2 bridges,2x47000uF, 2.2mH, 20x4700uF
A3(mono) contains 300VA, 2 bridges, 4x22000uF, 2.2mH, 20x4700uF
total uF (stereo) will be 244400+188000+182000=614400x2=1.228.800uF!! So special care should be taken with switching on. The caps will be loaded with large 100R and after 1 minute full power will kick in. (with a programmeble timerelais)
Here are the first pictures

That looks serious!

What are you using for the active crossover?

Im using a nice 24dB LR filter from BMM-electronics

Maybe later I will build something else, dunno yet

I just finished wiring the main part of the power supply, many more wiring will follow...

where did you source you chokes from?

Will be interesting to see the thermal management! - looks very nice work

[aaronboumans]

Chokes where bought here;

If thermal problem will occur then fan fan will be installed and will be places in another room (noise) or something....

today installed 3 Thermistors (5Ohm ntc)+10 ohm resistor to repress inrush current. After 40 sec's they will be bridged.
So far so good! Then installed 1 Aleph 5 en that worked as well!
Old speaker; and there was sound!!!! yes!!!
And you can feeeeel real power and control, Je**s this is nice!
No hiss, buzz or anything! And dynamic range !
I like it, will continue building and will send some new pictures soon.
By the way, how hot can/should the heat sinks be after 1 hour?
What can be tolerated?

show us a copy of your electric bill after one month of operation. I think you could power a small city off that array.
