Echo Base - a new PT2399 delay

[matej_mlody]

I tried prepare this PDF but I can't check appropriate size. I don't have printer in home. Can someone print this PDF and check it with several elements? I  print this image to pdf file, I used to bullzip PDF printer and next  Foxit PDF editor to rotate image. Sorry my english is not really good this link to pdf http://www.speedyshare.com/files/25858037/echobase_VER1.pdf

[deadastronaut]

this brings me to the question...

why do we always have to resize?....surely this breaks up/squares/pixelates the image,

or is it down to the author...hmmmmm.....you would think it was ready to print on a pdf eh?..

perhaps you are looking the gift horse in the mouth a bit?   

yeah, perhaps..

i just thought the original author would have it ready to print, if they were going to the effort of putting it in a pdf..just seems like it would make sense
rather than resizing every time...

Here, I've made a ready to print pdf from anonymousfacelesscoward's layout:

just hit "download document"

[matej_mlody]

Barcode80  Thank You! I think that very much people will be grateful for you. Greetings!

Why do you post the old version again?
The buffers in that version produce way too much hiss. (That´s why I never used my first version Echo Base!) 
There are better layouts from Taylor and Dimebugg that include the improved buffers that slacker posted a while ago...

[matej_mlody]

So... Could you give here 100% correct the best of project echo base? From Taylor and Dimebugg latest final version.

Edit:
I looking for this layout from Taylor http://www.aronnelson.com/gallery/main.php/v/Taylor/ but I don't see PCB layout, in pdf documents is only parts of list but not PCB layout. Hm...

[El Heisenberg]

Crap, I just got done building a PT-80 that you could switch in the delay block for the SHecho. I thought I was all sitting high but dammit, now I gotta build this. Got chorus and vibe?? Aw man.

taylor's layout is for his prefabbed board which is multi-layered and can't really be etched by hand. If you want to use that one, you will have to buy a board from Taylor.


for that pdf i posted, i just picked the first one, forgot that it had been updated for the buffering. I'll correct and re-post in a bit.

...that´s a good choice, I think. His board looks very well-made and it´s quite small.

If you want to etch a board yourself, use Dimebuggs version (posted a few sides back)

btw: Does Dimebuggs version fit into a Hammond-B enclosure? If I ever built the Echo Base again, I would really like to make it that small.

PCB measures 5.4cm x 5.7cm.

Passt.

I made a list of all the mods I found in this thread, correct me if I missed one. It's hard to always search all the pages for a specific mod.

Is the tap tempo mod really that easy to build? http://www.diystompboxes.com/smfforum/index.php?topic=60662.msg628311#msg628311
I know there is another thread http://www.diystompboxes.com/smfforum/index.php?topic=81668.0 but I'm really tired now I'm going to read it tomorrow

The PTAP is no longer available. The only thing right now for tap tempo PT2399 is that Taptation available in Aron's store at the top of the forum. But it also hasn't been available for a while. I think Aron will have them at some point.

[slacker]

Check this out http://www.electro-music.com/forum/viewtopic.php?t=45688&sid=2a706a4dceffdc3a9bb89a3efff31ba1 the Echo Base goes modular

[Taylor]

Ah, cool! If I ever get the time to begin my modular, I have 4 EB PCBs built up for it with pots wired that way.

[DimebuGG]

btw: Does Dimebuggs version fit into a Hammond-B enclosure? If I ever built the Echo Base again, I would really like to make it that small.

I housed mine in a 125-B enclosure with a lot more spaces left. Bet it would fit in a 1590B types.

[mr_deadmaxxx]

hey slacker..
how do you turn ON this circuit?
did you connect the 9V to the input jack so it would turn ON only when an input jack is inserted?
is the 9V still supplying the circuit even if it is bypassed?

[slacker]

You can wire it up so the power is only on when the input jack is inserted, just copy one of the wiring diagrams at General Guitar Gadgets or whatever. I never bother doing that though because I only ever use a power supply and that is only really useful for batteries.
Like all pedals, the power is supplied all the time whether it is bypassed or not.

[cctsim]

What is the best place to buy the PT2399 chip in UK ?

I found it is available here:

http://www.doctortweek.co.uk/

Is this a good supplier ?

Thanks in advance for any help.

[slacker]

I've never used him but other people here seem to like doctortweek.

[cctsim]

Many thanks.

One more thing, Will the strip-board layout fit in a Hammond 1590B (119x94x30) enclosure ?

If not what is the best enclosure dimensions ?
