Pearl MC Pre-Preamp - Page 3

I have some news.
I changed the layout again.
I am not quite finished but the Board will be even smaller.
105mm x 63mm.
That means the board can be mounted lower and nearer to the Pearl Board and not on top of the MKP output Cap.

The PCB will be mounted on the Pearl with 3 plastik distance holders of 15mm which will be glued on the Pearl PCB.

I will show some picture how this works.

Sounds nice promitheus, becaurse the chassis's i'm using only has about 2 cm over and under the pearl.

So here is the new layout.

promitheus · 7th May 2006, 09:28 AM

one more of all layers

This is what it will look like in real size.
If you will use the board separately you can mount it using the 4 corners.
If you want to mount on top of the Pearl you have to use the 5th hole on top beside the 150nF Cap.
This must be done because the top right corner is directly above the Q4 ZTX450 transistor of the Pearl Board.

For the 3 corners on top of the Pearl I was thinking of something like this.
You can stick these to the Pearl board.
They have a sticker on the bottom side.

For the bottom left corner which is at the same position with the Pearl screw there are many way to do this.
The easiest is to use a long screw and fix the board with 2 nuts.

Any updates on the progress of the MC boards?
The most recent layout looks really good.
