MXR Flanger Circuit Board

[shredaholic]

Would anyone be able to source/make/design a circuit board for the original MXR flanger? I've got the parts necessary to build one, but I don't have an original to copy from - just a schematic.

Did you find a SAD1024 chip?

Re: MXR Flanger Circuit Board

yep - smallbear has them. I've yet to purchase one but I know they've got them, it's $14.99.

I'm planning on using a 9v supply then bumping it up with a MAX1044 instead of using the original's power transformer. Also, I'll be using a 3PDT switch and LED unlike the original.

Now that sounds cool. I'd love to hear some soundclips of that. KEep me updated man!

Will do - once I've got someone that can help me turn my schematic into a neat PCB layout, I should be ready to build it.

Why not just hardwire the sucker??
Hehe it will get really hairy and fun

Re: MXR Flanger Circuit Board

lol I've thought about that, but judging by the size of the stock flanger, I'm concerned that hardwiring one would turn out huge!

Here's the schematic (excluding switch, 9v to 15v supply mod and jacks):

That free holeboard is the first ever Delayla XL, it was hardwired
Just imagine how it looks underneath

Re: MXR Flanger Circuit Board

That looks very neat from the top, and no bigger than the final case. Do you think I'd easily be able to hardwire the Flanger and make it fit into a case the same size as the original then? (Using one of these: http://www.smallbearelec.com/Detail.bok?no=73)

Also, what type of wire should I use - solid core or stranded?

Here's the case I'm planning on putting it in:

Re: MXR Flanger Circuit Board

Hardwiring this Flanger is a total pain in the ass Rid - how did I let you talk me into this?

I'm at the point right now where I'm really considering starting again with a proper PCB, as I've wired it all up but it's not flanging and I've run out of things to test. The problem would there be finding someone to do the layout for me.

I'll give anyone original MXR factory schematics and the PCB layout diagram(minus traces) if they can design this layout for me.
