Hi guys, i found this site googling PCB etching and thought i'd ask a question as my first attempt at etching was unsuccsessful.
I am tring to make a new board for an old 70's guitar amplifier which is valve driven. I copied the circuit layout and transfered it by hand using a permanaent marker pen. However, when i etched it, many of the tracks show severe degradation, likely where i havent gone over the tracks well enough with the pen. Since this board has to carry ~ 500V dc/ac is there anything you can recommend? I read some tutorials from here, but i have no laser printer, just inkjet.
I think one problem was that i didnt prepare the board well enough. I just gave it a wipe with acetone. I'll try shining it up a bit with some fine abrasive, but i dont know whether it will give better results. I also have a DECON PC33 marker that i got from Maplin, would that be better to use?
