Thats interesting. Im learning new things about these synths all the time! So how many different transistors were used here? 4?
C1815, C1685, 536 & 945's im aware of so far..
Also, when these different transistors were used, were they the only thing that was different, or did anything else have to be changed for them to work as intended?

I'm thinking of socketing some of the components that have been identified as important for sound and then trying out a few combinations. But before I do that I might just focus on making some actual music with the x0x and stop worrying too much... ;)
Socketing is a good idea when you want to hone the sound of the x0xb0x. My first build, I didn't use hardly any sockets, so changing the odd part was a bit fiddly (I changed quite a few when trying to hunt down a small fault too). So in my second x0xb0x, I socketed just about everything. Only to find that it worked perfectly first time, and I loved the way it sounded without needing to change a thing! Typical..
I couldn't tell you if that 2SK118O is good or bad though..
Anyways, yes, just use the thing! ;) It sounds good to my ears.

Hi all,

I've just have one from TBS. No problem, I'm very happy with ! It sounds very good. I never have an original, but I listen often to some Underground Resistance tracks, and form me it's very similar... Probably the sawtooth creaks more...
I've it with UPS from Germany to France in 3 days :wink:

Bye

Hi,

i got one from TBS...well.. seems "correct" mounted (i no dissasemble it yet), but i'm not sure for the sound quality, not so much scream for my taste, by the other hand 2 days Germany-Spain.

There's any pattern (well, i mean a clip) that i can check with a good x0xb0x to compare the sound?

Edit: I test the pattern post by buddax and the sound it's not right...seems that be less resonance on it... and the lights don't shine (well.. i don't expect the sunshine on my room.. but there's a poor light)

Hi godbeat,

maybe I can help you with this Sound-Check.
Its the same Unit from that Seller - now repaired.
"the specialist" =] put some magic in my Xox and now it sounds great. great job !

soundfile:
http://ul.to/ajyy77 (doesnt work for me)
EDIT:
http://www.mediafire.com/?ok9m9myiq45qyqo

pattern:
( g1 s = g, one octave higher with slide )

-SAW
1. g1 s
2. b1 a
3. g#1
4. g#2 a
5. g2 a
6. b1 a s
7. g#1
8. g#2 a s
9. g
10. b1 a
11. g# a
12. a# a
13. g2 a
14. b1 a s
15. g#1
16. a#1 a


The LEDs are ok, they glow like every other LED in my room under various conditions. (my equipment-room is "direct-sunlight-protected") =]

thanks chessypuff!

I ask to "the specialist" and he gives me the clue to do the repair.. now i'm waiting the correct supplies to start the work :-)

I'll check the pattern with mine.

My led, just TBS said "the purple LED´s are a bit tricky (that is unfortunately the nature of them)".. but i'm sure that's not right, i'll check the resistance values when open it to change the components.

if you want reference recordings theres a stack of tb303 sounds i made especially for this on my blog under the x0xb0x catgory

@ CheesyPuff

Who is your "specialist" ? I would like to ask him for some questions :idea: As he looks in your one, probably he could give me some information on what to check in mine :wink:
I'm globaly happy with my Xox from TBS, but probably it could sound better with a tunning and some parts replacement... The fine tunning game 8)

In fact, I'm a little desepointed with the bass sound (C1,Filter quite closed and reso half open). For me it's not clacking enough. The attack look a little to slow and decay too long... Anyway, the resonator seams good and opening the filter is so good, so analo :twisted:

Cheers,

Hi guys, I just received a Technology Transplant x0xb0x knockoff from a seller in the US (who will remain nameless cause I want to see if they give me a full refund or not), and it is absolutely terrible. The knobs hardly do anything, and when I received it there was a loose screw rattling around inside the case. The decay knob does absolutely nothing and the others make a very slight difference to the sound. Irritatingly, this was to replace another x0xb0x I bought on ebay that didnt work, and now Ive to send this one back too! I'm seriously starting to lose patience. Short of it: Avoid TT's x0xb0xes at all cost! They're apallingly bad.

Hi,

Here is my experience.

I bought it in July/August.
I was not satisfy, it sounds too soft, not enough content... Mostover, yes it's not hand made and the Tune was not totaly weld !

I sent it to Brain BANNED @ BC Audio - http://alphazone1.com/x0xi0/about/ to install a Xoxio kit, and to check the initial board (really nutty kit !)

He swap and intall :
- 9 2SA733AP PNP
- 6 2SC536F NPN
- 1 2SK30A (O) FET
- 1 2SK30A (Y) FET
- 2 encoder, Grayhill 25LB22-H

Now my box on OSC1 (the original one) is absolutly better ! The sound really slap, the filter and env are dramaticaly better, really close to the original, and perhaps better !

So yes, the XOX sold by TBS are not good ! It's said.

PS : Thanks to Brian, very great work 8)

This is an older thread but maybe this is helpful for others:

'
Q13, Q14, Q15, Q16, Q17, Q23 => C1815 instead of 2SC536F'

I checked my TB303 and saw that the transistors mentioned above are 2SC1815 .

So i changed them in my X0xb0x from 2SC536F to 2SC1815 and now both boxes sound the same...

As i understand there seem to be different versions of the 303 . Does anyone know how many different versions are out there?

I am very pleased with my 303 sound...i used to have a 2nd 303 which sounded a lot thinner...

I write this because the author wrote that he was confused to find 2SC1815 in his X0xb0x from TBS, but my 303 is fitted with the 2SC1815 originally.

Hi guys
I got my modemachines(tbs) xoxbox before 2 weeks did some modding too
And i made a full parts listof my box ( the transistors)
By the way i dont really know if it sounds like a real tb bcoz i owned 3 tb's and every tb sound quite different in filtering etc. So mybe yes ? The only thing i really noticed what is a mayor difference is the sawtooth the ones in the tb 303's sound all smoother
I also tried the mod with the pot instead of the resistor r1 and nothing changed from value 0ohm to 500 ohm sounds all the way same ..... So ok here' s the list of the parts in my xox

Q1,2,8,9,10,27,31,33,36,38 are all the same type A733K 07C written on the transistors

Q3,4,11 are. H945K 2K4 no C536F
Q13,14,15,16,17,23 are C1815G R4E also no C536F
Q5,24,25,32,37 are C536E 6E also no F why so ever
Q18,20,30 are C536KE 6A also no F
Q19,29,34,40,41 are. C536G 7K also no F
Q35,50 are C536F!!!!4M the ones thatshoud be?

Q22 is a C2291 11F
Q12 is a C1583 82F
Q21 is a C1583 3ZF
Q26 is a C1583 4XR
Q28 is a K118 never heard abot this ( K30AY or AO)
Q39 is a K30 AY4L <- this one is called in my xoxbox Q3S? Why ? Dunno.....
IC21 is a 78L06 so ok
IC22 is a LM336Z5 also ok

The ic 14 and ic 15 are the ones that should be also
So maybe someone can explaine me why ther is so much difference in the parts that r put inside my xox and the parts u get with theoriginal kit
And what it makes with the sound...?
I do belive that there are also many different parts from tb to tb ....not belive i am pretty shure coz u cant tune a tb to sound like the other ive tried it with my 3 and there was no chance it was their own character so mybe the modemachines guys do the same with the xoxboxes?
For my uses its not really important to have a 100% copy of the tb 303 b.coz at the gigs and on the final mastered recording noby'll hear a diffrence even not if i'd use a softwareclone
I only want to know whats going on with this boxes.......and if it is something like a 303or more like anacidlab bassline .......
Kind regards

Wow. they just seem to throw whatever NPN parts they have at these things.. All the ones u listed are used in 303s at some point , the codes relate to the beta (hFe) of the parts

CLASSIFICATION OF hFE
Rank D E F G H
Range 60-120 100-200 160-320 280-560 480-960

So the a733k 07c r good where they are?
And should i swap all the c536's to f''s?
Also whats about the h945k's thats the only thing that i dont understand and that i never heard from
Also the q28 that is a k118 should i swap this one with a k30 ay or ao
This k118 r also ones that i never heard from .....

They told me it made with theoriginal parts from the kit ....asi said no ,they told me that they have recived this parts and this pcb's from adafruit ...... LIARS

Thank god i have a verry good electronic supplier in my hometown who vcan get me all the parts alsothe rare ones ( they told me that the parts r not really so rare they get only unused wit the time so nearly noone have them anymore ) i ordered them today it was damn cheap now i wait them till next week to fix my xoxbox and see what happens
