Wrong.

At the rear has no fan. Just got the grill.

On top the fan is to extract air out.

but you tried it in the back? blowing air in? or sucking out? and this was not so good as on top sucking out air?

A fan or pump always works more effectively "blowing" the fluid.

A fan in the bottom of a case blowing up will perform better than a fan mounted on the top sucking up.

You just have to be sure not to turn your equipment into a vacuum cleaner :-)

Blink_PT,

How did you fix the PSU capacitors to the bottom of the cabinet ?

Thanks,

D.

They are based on a bakelite isolator plate with duct tape, double-sided.

The copper plate has two holes (see in the picture), now with a plastic clamp, but it will take two nylon bolts.

Another F5 finished, my first power amp, be clement

Boards come from diyaudio store, component from my box ( capacitors and diode bridges) and mouser. matched fets from spencer.
The first step, components soldered, and first turn on. The heatsink was too small... too hot...
http://sdrv.ms/Yz6XET

hifi2000 chassis, with main components.
http://sdrv.ms/11xeniD

Psu in place temporarly, because a problem of buzz in the speakers, I put the transformer in the other side of the chassis, and change the input cable to a shielded one from selectronic.
http://sdrv.ms/11xes5P

Final place of the psu, the transformer is holded by a metal part from computer chassis, and linoleum to prevent from damage that can be cause by metal part (maybe replace for better later). Conrad doesn't supply part to hold the transformer...
The capacitors supports was made by a 3D printer of a friend.Made to measure

The front power switch is the same as this one :

Thank to nelson pass for this great amp, and thanks to all people that ask and respond to all technical questions that make this forum so rich in terms of knowledge.

Default %$!&%#@!!!

Need CSI DIY

I probably know the answer, but is there any way to salvage a toroid?

You know the story - " I should remove that toroid in case the drill grabs and........ ". The outer three layers are cut or distorted.

Not expensive to replace but I thought I'd ask the question anyway. Isn't quite the picture I had planned to post this weekend.

Drill out the core filling.
tape up the insulation both sides of the damage.
cut and remove the insulation to reveal the windings.
cut and count the turns that you remove. Try to just remove the outer layer/s.
If a deeper layer is damged then remove that as well.
You will have to be sure which windings you have exposed by measuring back to the original lead outs. Sometimes the manufacturer uses slightly different colours of enamel on the bi-fillar windings.

Now wind back on the required "patch" turns to repair each layer in turn.
Insulate the soldered joints very thoroughly.
