Modding the Philips EL6425 - etching brass

Time to etch the brass I cut yesterday.
Started by transferring a print to the brass.

The etched brass after I put it into a mix of sodium persulfate (natriumpersulfat) and warm water.



Time to paint : )



After removing the excessive paint.
Polished with brass cleaner.



And here we go, I'm quite happy with the result.

So I want to shield it by putting a brass panel with circuit board material underneath.


Please do not touch..



Cutting the circuit board and the brass with my dremel.
The circuit board will act as an insulate for the brass.



And then put them together.


And some testing to see if it all fits.





And finished! : )
The next step is to etch the brass.

Modding the Philips EL6425 - taking care of the ugly-as-f**k chassis

Right.. The chassis really is ugly.
I want to keep the 60's feel and bring the tubes out in the free..
I contacted Johan at Mattssons Smide http://www.mattssonsmide.se and asked him if he could cut the chassis. He pondered the idea for a moment and said, no problem.

Thank you, Johan!

Next step is to paint and lacquer the chassis.
