Hi Idefixes,

Are those 5W metal films or are they just 3W?

Here are what i ordered : 286-0.47-RC Xicon | Mouser

 

[Idefixes]

Some little progress : Bias BJT, Driver BJT and Output BJT as Output coil are soldered

 

[Idefixes]

Populated board are screwed on heatsink. Yet i can process to built whole chassis.

What's that huge 1uF cap for?

Mundorf Mcap Suprem : not buy specialy for Nbip just have them on hand so decided to try these puppy on Nbip.

Hi Marc

Very good PCB-s, quality parts installed, perfect build. I especially like case layout from the pic.

Thanks LC. There's a little bit TSSA BIGBT spirit in pcb layout. I decided to change it after TSSA routing job supporting from you. I will finish Nbip casing job and swap on TSSA BIGBT HP.

This is a most impressive re-design of my humble little amp. I've checked out your site and the link to the french audio site, well done indeed. The cabinet is awesome too. Congratulations Marc, nice job.

Hi quasi glad to see your intrest to my interpretation of your work. Nbip is a relly good project for poor electronic knowledge as me. He seem to be rock solid and well documentated. I work on it quite a long time wich mass of differents routing work. Lasy Cat coatching on TSSA project bring me to rerouting completly the baord. I must update my home page since Nbip design presetd on it is the older version. Next step is to built de case (i go on store for materiel this afternoon) and wiring the amp to ste bias (150mA per side). The sound won't probably surprise me as i use every day my Nmos200 just a evolution of it...

I have an Artck in project to for sub driving.

Some progress on my Nbip case building

So the Nbip3 play his first music note this afternoon. Bias set to 150mA per side, offset trimed to 0 (thanks all transistors matching). As Quasi said the Nipb is the the same as Nmos (200 for me) but better. A powerfull smoothness with a soundstage balance as i like : air between instruments and singer from rigth to left and from front to back ...Next step i unconstructed it to apply the finish

excellent make Idefixes ...really well done !!!!the R core is lovely i presume that costs a small fortune ..
good work
Kind regards

Thanks Sakis,

At normal price yes it coast 120€ ( about 140-150$) but i bougth 5 fives pieces of them (500Va 2x36V) at 29€/piece on reduced prices periode....

posted please the pcb,

This is the PCB i use : http://www.diyaudio.com/forums/solid-state/88258-brother-quasi-42.html#post3057178

I have some other iteration on this layout that using MPC71 for emitter resistor.

Don't care about Led3, C7. I don't mount them. Right value for R12, R15, R8 are schematic one i jointed here.
