New-building of my F5

[enzedone]

Oh yeah

This looks extremely nice



Your just too fast

This is amp pcb plan, based on the circuit in the post #3.
Don't look seriously into the thicknesses of the tracks because they will be adjusted in actual building.

100% done?

No, power Mosfets, thermistors and Jfets are not soldered yet.

You didn't have any problems with the drilling of holes?

Nice heat sinks

Hi
I really like you hand drawn layouts and boards! What type of marker do you use and how do you clean them after etching?

Thanks

 

[Nelson Pass]

Happy to see you doing well, Babo.

 

[Babowana]

Thank you, Papa.

Best Regards,

For drawing I use the oil-based marker (permanent marker) which we can easily buy in the stationary shop. For cleaning after etching I use the rough sponge in the kitchen. I rub the finished with the sponge in water.

Now I believe you when you say "kitchen". NPaPass fessed up some time ago that FW amps are really not from his kitchen.

Mr. Pass always shares his recipes. And we all have big smiles pasted on our face when we cook his masterpieces.

Re: Sweet

When I was buying the heatsinks and 2mm-aluminium plates, I asked for the holes too. But, the shop said that they don't have man-power to make any hole. Pity . . .

I decided to make the holes myself.

My normal procedure is:

1. First, I make hole puch marks to the right hole locations. The aluminium plate or surface is very slippery for the drill ends. So, I put the punch mark for the 2mm-drill end not to slip.
2. Second, I use 2mm-drill on the punch mark to make the mark bigger.
3. Third, I use 4mm-drill to make holes for 3mm bolts.

   The photo shows marks after finishing 2mm-drilling.
   
   In order to make the 4mm hols straight, I also use a special tool. I will show it to you later.

Now making holes . . .
I changed mine. I'm drilling 3.2mm-holes, not 4mm.
Do you see the drill stand (or drill guide or whatever)? It is a very convinient tool for my diy work.

Drill guide

Yes this is great, I have never seen one of these before. I will have to try and find one these.

Dang, no wonder my holes are all crooked.
