MN3007 version eh clone theory...

[pinkjimiphoton]

has anyone actually built one of these?



i've been thinking about building one of these for quite a while, i REALLY regret selling my original one...

i can get the chips locally for about 10 bux, i'm assuming the sad1024 is hard to find and/or very pricey.

little help would be appreciated, thanks!!
peace

I haven't, but it isn't terribly different from a 3007-based Small Clone with mods.

The Small Clone will run off a 9v battery.  The Clone Theory wants a 15vdc supply, and uses a transformer to do that, but there isn't anything particularly different about the LFO, clocking circuit or audio path that would demand enough current that a transformer is a must.  It may be sufficient to run it off a 9v, or perhaps a pair of 9v batteries feeding a 12v regulator to provide a stable bias voltage.

thanks mark.
the clone theory sounds a bit different than the small clone...the big thing is i hate to invest a bunch of cash i can't afford (there's that GAS again...ahem!!) into something that may not work out.

but i appreciate the response! i found a verified version on vero in the gallery, will probably run it off a charge pump so i can run it off my pedalboard's power supply.
working up a BOM now to see if i can afford the parts from mouser...i traded my original in at daddy's junky years ago to help a neighbor get her kid his first guitar, figuring i'd pick it up the next day when i got paid...

but it was gone literally seconds after hitting the listing in their database. live and learn.

i THINK at this point i am up for it...the mn3007 is the original version, so hopefully will all work out.

hey, if i don't cross paths with ya before then, happy holidays my friend!!
peace

[Mark Hammer]

And same to you!

[pinkjimiphoton]

thanks man...

just finishing a mouser order...dear god, the humanity....

WAYYYYYYYY too many parts!! 

and of course, an mn3007?

FUHGEDDABOUTIT!!

gotta go with an nte "replacement"....nte1641, let's hope the pinouts match!! lol

[Mark Hammer]

Not to worry.  They do.  I believe I used one on the CE-2 clone I "accidentally" sold for $5 (long story, involving a mistaken confusion between two charity auctions).

[pinkjimiphoton]

ahhhh....cool!!

but...i said screw it, and bought a 12 pack on ebay for less than the nte would have cost me!


ordered all my parts...with a bit of luck, i should have everything here in the next week or so so i can start building it!

Hello Jim,

I've just finished a clone of Clone Theory using the layout of Paul Nelson (thank you a lot Paul for all your projects!): http://sites.google.com/site/electroconducive/ehxclonetheory.
It sounds amazing and I like it a lot. I didn't try any of the suggested mods by Paul because it's not clear for me which are tested.

I tweaked the trimpots by ear, but I am curious if there is a more scientific method to do that

Best regards,
Radu

I built it with a 3007, sounds gorgeous...

[pinkjimiphoton]

thanks guys for the headsup...cathexis, i'm using your vero layout, so that's great to hear!!!

was my favorite box, the first one i ever bought myself....nust have been 77 or 78 or so.

i'll be implementing some tweaks probably, radu, maybe pauls, maybe my own.

there was one peculiar setting on it, where if ya got it JUST RIGHT on the flange/vibe-chor/vibe switch in the middle, it sounded completely different...i used to think it had both effects on, but now i suspect it actually kills them.

whatever, i can't wait to build this thing!!!

thanks guys!

[gigimarga]

Good luck Jim!

[pinkjimiphoton]

THANKS BRO!!

[pinkjimiphoton]

hey guys,
i re-did cathexis's vero layout...no changes really, tho a couple of part numbers may be off, i included a bom with the components as relevant to my layout. i was having a real problem trying to see Cathexis's original layout, cuz my eyes are buggy..i mean absolutely no disrespect by re-rendering it here!! 

parts are ordered, be starting on it soon 

to make it as easy as possible for such a component-heavy project, i made 3 boards....one from the strip side showing all the cuts:



one the same, but as seen THRU the board (from the component side)



and finally, the actual layout, which i've checked over and over til my eyes melted...



i believe these are all good, someone with a better set of eyes would be welcome to check!!!!!! for sure!!!

but i think it's right...towards the right of the board in particular, the nomenclature of the parts order may be slightly different from c's, but
all the parts and their locations should be good.

finally, a BOM of the whole thing:

again, will be building this as soon as the stuff arrives, and if anyone wants to take the plunge with me, i hope you find this useful.
thanks to topopiccione, cathexis, amd everyone else involved...

blessings! 

[pinkjimiphoton]

found a mistake...no trace cut at strip w hole 3...my bad, will update the pics as soon as possible..

[pinkjimiphoton]

board done and populated...just waiting for the bbd chip to come in...this is one heck of  a densely popped board...man...alot of soldering...


also found one other mistake on my vero SO DON'T BUILD FROM MINE YET...USE CATHEXIS'S!!!

pics to come later today if i get a chance.

hoping it all works when i finally button it up...this is the most complex build i've tried yet i think.

stay tuned! 

[cathexis]

Good job on the layout! I started drawing mine by hand just because the layout program got really slow with big layouts, and because I could do them away from a computer. I never tried anything that big in the layout program - looks great!

[pinkjimiphoton]

thanks bro, it's YOUR layout, i just copied it. there is a mistake or two on it tho, i have to upload corrected versions as soon as i get a chance.
i'm waiting on one 10k pot, and the mn3007....and then it's time to fire it up!!

i can't wait.

did you use a charge pump on yours, or do you use a 15v transformer?

i bought a wall wart for it, hoping that'll do the trick. i'll post a couple pics of it so far in a minute.

[pinkjimiphoton]

[cathexis]

did you use a charge pump on yours, or do you use a 15v transformer?

I used an 18v transformer with a 15v regulator on board, that worked nicely. I did the same thing on my ADA flanger - which I think you should build as well, since you seem to be man enough to take on monster vero layouts That one is my all time favourite modulation pedal, it does pretty much everything and it does it beautifully. Check out the layout and some soundclips in my gallery...

[pinkjimiphoton]

lol...man enough? it took me ten years to get the baalz up to tackle this!!

thanks for the transformer info...seems  i should be ok with the 15v one i ordered then hopefully...be a laugh if i had to step it up!

have a great new years lars, thanks for YOU being man enough to tackle this project...and showing the way! :thu:
