Hi guys,
I'm in the midst of building a 5.1 system for watching movies, and am looking at amplification for the centre/surround speakers.
After lots of prototyping (thanks to my dad there
) I've decided I like the sound of the ESP 60/100w amplifier, loads of clean power, perfect for action movies
But I've decided to go all professional and put the amps on (drumroll) PCB's. Problem is that I want to etch the boards myself, and not buy them. I can't seem to find anywhere I can get the foil pattern.
Can anyone help out?
Thanks

Dunno really, just fancied doing it myself.
How about the Leach amp, I've heard quite good things about it, but to make a PCB I need the foil pattern as an image (I like to use a product called press'n'peel, which needs the image to be flipped vertically and horizontally, which I cant do when it's a PDF file)?

PCB Layou and Design
Hi
I'm making a Leach amp at the moment, did the layout myself

Making your own boards
If you really want to make your own boards, G.Randy Slone's are available in his books (you may need to enlarge some to 1:1 scale) or if I'm not mistaken you can buy construction manuals for some that let you use a copy machine to make transparancy for photo etching or to make a iron-on-peel sheet. He'll sell you the boards too if you wish.
Be warned, his parts counts are quite bit higher than Rod Elliot's. Many of his designs seem to be variations on Doug Self's "Blamless Amp". If you like low THD, they don't come much lower in AB class.
