Very nice from the outside Mikael but Mr Flibble seems to have lost the interior shot!

Hey Mr. Fibble-

Very nice.

How'd you fit that torid in that case!! Must have slid it in from the end...

Thanks,

Troy

You are right. It along with the copper bar is mounted on a 2mm alu plate. And do notice there are no holes on either side of the case. : o)

Mr. Flibble-

I just "assumed" you had bolts sticking out the other side.

I see now... You used the PCB slots for the 2mm Alum. and that is what holds everything in place.

OUT STANDING! Really nice and elegant design.

I may do something similar for friends who request a GC.


Thanks,

Troy

Nice. I was looking at that case a couple of days ago, nice and small. What size is that transformer? Is that your own board design? If so could you post something for us to print to etch our own boards with?

Thanks
Steve

Its only a 80VA transformer although there is room to fit a 120VA.

If you can mannage to bend the bottom (the slide in bottom) in an U shape or accept a bolt trough one side.

The toroid is wound to have 2x18V windings wich gives about ~35W of outputpower so I got more than twice the amplifiers rated yield and I feel pretty comfortable with that.

The board are the same as those availible from BrianGT although I used 1000uF/50V Elna Silmics instead of the FC:s

Before the days of DIY hi-fi, men used to put ships in bottles to pass their time away. Now Mr Fribble has brought the two hobbies together!

Yes, very well executed. I would not have thought that an amp and its PSU could go in that tiny case!

It cuts the cost of using two cases, extra sockets and an umbilical cable!
