It is the ancestor of the x0xb0x. I think the x0xb0x has changed the life of many people. Ah, ah, 303 subscribers, you don't have to subscribe anymore.

Other question, i still have 2 clones of korg 35 left. Nobody made a PCB to have a 35 filter, for modular? On which we could graft the korg 35 clones. Or a vero board? It doesn't exist? I searched on internet and saw only OTA clones...

Ok, thanks.

Hi, i have an MS20 korg 35, KLM127, the auto-oscillating filter too much, it's bad for the synthesizer play. It has an abnormal behaviour, it's not much, but i find it annoying ... I compared against 2 other MS20 equipped with Korg 35, here is OK... Mine itsn't OK. I replaced the Korg 35 by DIY clon...

Hi Alain, i remember well your MB606 on the anafrog forum. My bug first appeared about a year ago and worked fine for 6 months after that. For the last few months the problem has persisted. It's possible that a cherry swich is messing up, i hope that's it. But if i remember correctly it is not alway...

Everything works, except that it randomly changes the pattern on its own. It's like MB808 but more elaborate. It has nothing to do with nava, the only thing in common is the instruments, it's a much more powerful sequencer. MB909 can sequence several drum machines and synthesizers simultaneously. I'...

Mouser is a professional site, often a little expensive, but with a lot of choice. And above all the components are of high quality. The good thing about them is that they have a head office in my country, yet they are an American supplier, in case of problems with an order, i always have someone to...

Hi, maybe you remember MB909 which had several names, it was introspectiv 9090 with a midibox sequencer which had an interface resembling the TR909. Mine worked well for several years, but it was difficult to get something that worked well, it took weeks of work, you can't count in hours. ;) Mine is...

Hi, you're Swiss and you speak French? I know someone in Switzerland who does a lot of DIY.

I am missing less than 10 knobs. I'm thinking of buying those from aliexpress as i can't find a better one. Sifam does too. The ideal would be shaft with the flat, not screwed.

Hi i've been searching for some knobs for PC16BU potentiometer: https://www.omeg.co.uk/wp-content/uploads/2020/02/PC16BU.pdf The problem is that it's a 4mm shaft, it's not common. I bought cheap, a soundtracs mixer on which some buttons are missing... The ideal would be to find adaptable knobs from ...

I had watched the whole thread, i don't know why i didn't seen.

There's no one who can tell me about R42 and R36? Because i don't know how many ohms they are, i can't find them in the BOM...

You should buy the RE-303 PCBs, with a bit of dremel the case will fit, you also have the knobz you can get. That's a good excuse to build a RE-303.

Since the time has passed and i've made something different out of it. I removed the fuzz but installed a monotron VCF on the master output instead. And i added pitch and drive mods on the toms. But i've built one for myself and i won't build another. Because i think it's pretty risky to try to make...

Wouldn't your switch be a momentary one? Or a faulty on/on. Otherwise there's a problem with the envelope

bass boost: https://www.subatomicglue.com/x0xl0g/mo ... _boost_mod

Btw slide timing, if we do the mod in such a way that we can really hear, a lower pitch of the slide, irremediably the tune of the VCO will be a bit lower.

Hi never built steiner parker, but pay attention to a small detail, there are 2 kinds of 2N2222 with different pinout. There's 2N2222 et P2N2222, maybe this.

Has anyone got one of the pcb's? I'd love to do that mod to my 2nd x0x...it might help boot me back up to finishing it! I am working on a 2nd VCO for x0xb0x, but it will be different, with an additional VCO level potentiometer, a fine tune and sync: https://www.youtube.com/watch?v=10ydEgjDAcs I wil...

Hello, there are 2 resistors that i don't see in the BOM. R42 on the switching board and R36 on the highpass board.

My problem solved, my -5VDC power problem was because of 7915 that were labeled 7905. It's the first time in my life that I've seen this... It's ST they're labeled L7905CV 99205. Replaced by a motorola MC7905CT, problem solved. But i wonder how it's possible that a manufacturer could make such a mis...

Yes KSS, if i had done that reversal 78xx/79xx, regulators would have burned out.
Here, i've got this at IC20 and no short circuits:

Yes, i removed it and soldered another, 7905, still the same problem. I'm going to try one on another circuit, maybe they are faulty. It's strange.

Hi, so far i've only built that power supply, i've got a problem. When t ordered the BOM to reichelt, the 4700uF 40V capacitors were unavailable. I soldered 4700uF 25V instead i thought it would be OK, i must have been wrong. :doh: IC19 is ok, +15V IC21 is ok, +5V IC22 is ok, -15V IC20, is bad, and ...

I just ordered all the components to build it. (I had bought the PCBs last year, built was pending). I should start the year well by building this vocoder i've been dreaming about for a long time.
