BK's β24 build

Postby bk_856er » March 11th, 2018, 9:04 pm

Phase 1 complete: boards now populated!

I started, or should I say acquired all the parts, about 5yrs ago. Finally found the motivation to start after I noticed the printed Mouser labels were fading into nothing. Based on Ti's schematic date, I think this will end up being a 10yr anniversary tribute build. :D

More to follow as things (slowly) come together....

Wow, I forgot that it's been 10 years since the β24 was first released. Time sure flies! I plan to build another β24 for myself some time soon. It will basically be identical to the existing one.

Question to all. When ordering the reference "Hifi2000 Pesante Dissipante 4U 1NPD04300B 4U 300mm
enclosures with 10mm front and rear panels" from the diyA store, is it (1) best to choose the steel covers option, or aluminum covers, and (2) how to I specify a 10mm REAR panel? I'm not seeing a REAR panel thickness option, just a front panel option.

1. I had steel top/bottom covers, but I didn't use the top one, opting to have an acrylic (Lucite) one made by FPE instead.
2. I simply specified two 10mm front panels, one of them to be used in the back. I also ordered two sets of handles.
3. Btw Hifi2000 calls this series simply "Dissipante" now, not "Pesante Dissipante".

Best choice. Pretty thin steel can bend under heavy (power supply) load.

This is the (fast !) reply from diyA store on the front/rear 10mm thick panel topic:

"Please go ahead and order the Dissipante 4U then just add an extra 10mm front panel (SKU:1FRONT1004B)
Also, HiFi2000 advised me to let you know that you will have to find a way to mount it by yourself as this is not a standard product."

OK, it's obviously possible, as many people have done the same thing. The only thing I did to make this work is to add four thick washers at the rear panel mounting points.

Is buying from the diyA store cheaper than going to modushop.biz directly?

Good question on the cost! diyA store makes it so easy I never bothered to compare. Will check.

I don't think so. Prices were the same when I was buying a case directly from Italy couple years back.
