First One - mosFET amplifier module

[taccodude]

FO works fine with normal PSU, Heatsink goes up to 37C with 60,5V .Bass is a lot better with normal PSU. So SMPS is probably not OK.

SMPS with synchronized rectifier? hmmm its good for switching amps.

I must be honest ,
Not buying any First Ones , Love them though ! Very nice concept !
Read all the posts , (Most are) very educating
Would like to order 6 DC sense PCB's for some other project .
Can't make them myself in that quality for that price .

Thanks and cheers ,

Hypex is very slow in answering Mails.

Perhaps they have a 'summer holiday' shutdown?

First One GB members ordered modules and chassis

Hi Guys

All silver chassis plus First One modules went to travel the world. In a day or two all blacks will follow.

Best regards, L.C.

Looking forward to seeing the black ones. I presume the monobloc chassis are not ready yet? I was thinking of using these chassis from modushop - code 1NGXA288N Galaxy Maggiorato 230 (W) x 280 (D) x 80 (H). Need to work out the cut-outs I require. First time I am trying this and hope this does not all end up in smoke! Nearly ready to commit myself and buy the components.

buy chassis from LazyCat. i saw it, and it is piece of art, it is really beautilfull and well made.

Hi LC,

I didn't receive an invoice yet...

With original First One chassis everything is prepared, threaded holes, bolts, so very easy job to do.

Chassis is built like a tank from 5 mm thick Alu plates, brushed surface and is calculated for thermal dissipation correctly.

Decide for yourself.

Somehow slipped through. Please say what you need.

the heatsinks from galaxy maggiorato are not even close to support the dissipation of this amp.

I would like to order 2 Pcs. DC sense kit.

the 80mm are not, but the 150mm or 200mm are.

 

[smoothquark]

The C1 chassis does indeed look fantastic. However, I would like to fit into max 240mm wide chassis as monoblocks. Happy to wait for the C2 or C3 chassis if these are smaller. If the heat dissipation would be an issue, then I need to try and get around it or work on a different solution for my rack...... Would separating out the SMPS to a separate chassis help with heat dissipation and/or sound quality?

there is no galaxy maggiorato taller than 80mm.
hifi2000 have other chassis suitable but at a much higher price.

Hi, today I will present exact delivery info to GB members. Currently I'm in assembly facility controlling the calibrations and QC. In a few days 200 modules will be ready to dispatch. Quality takes time hehe

You personally calibrated the fabrication machinery for the PCB and SMT production?

LOL

Hi GB members!

Here's C1 chassis for stereo First One amplifier.

Dimensions:

Width: 440 mm

Height: 70 mm

Depth: 310 mm

Silicon pads for bottom feet are included.

Price 300 EUR net for end user.

First One module has best possible position in the middle of heatsinks, very good pasive ventilation thanks to optimal air gaps perforation openings positions.

C1 chassis enables max power dissipation ie. max output power from the First One modules at +/-63 V regulated SMPS.

Also enables use of two SMPS1200A400 (Hypex) or two DPS-500 (Audio Power) or one SMPS2000R (Connex), free selection choice left to GB members.

Top perforation air gap inserts can be natural silver, red or blue.

C2 and C3 chassis will follow soon.

Regards, L.C.

WOW

That's a nice chassis! I was thinking your chassis would be some rolled case fabricator order online!

hahaha

WOW

It's not cheap but it's also not expensive considering it's tier one all the way!
