Steda Electronics SR-909 Full kit

[Cyrax]

At the moment are only PCB and partial Kits at customers around the world. The full Kits with Cases are short before shipping. Thats the newest information that I had About this, no videos from a full build there

[Cyrax]

If we want to buy just the case, is it possible? If so, what would be the cost?

Yes, that's possible, but more informations comes in the next time! First, the preorders of the Full Kits where shipped.


Spoiler: The next PreOrder starts in February!

Hi, do you have a circuit diagram for this? What did you use to substitute the BA662?

You use the open music labs clone http://www.openmusiclabs.com/projects/b ... index.html

Look at this beauty
I have finished my 909 yesterday! The best, I have plug it in and it works! No bug fixing, I am so happy!

In my opinion, its great that it sound 100% like the TR-909 but the most parts are easy to order for repair I have check the sound with my TR-8S and my Sample-Library... It sounds perfect...

It was a pleasure to build this! I was so excited as the package arrive at my Studio. And that all parts in it makes it very simple.

I have checked all offers like RE-909 (No case at the moment and all parts must be ordered by myself) or Nava that's not like the 909 in my opinion. And I heard many problems with it. And, all Sets are more expensive as the SR-909! But this is awesome. It looks like the original, it sounds like the original, its more stable like the original

Happy happy happy

Cyrax- how did you get the case, as I didn't think it was available yet?

I just ordered a full kit over at Steda

[303monkey]

Can you tell me when my SR-909 was sent out. It seems other people gave al ready recieved theirs

[Cyrax]

The case is only at the Full Kits at the Moment.

Anyone know what kind of audio jacks this uses? I have the PCBs not the full kit and the BOM doesn't say what kind they are

I used NEUTRIK NRJ4HF

You only need mono jacks, although the PCB has extra holes for the TRS version of the jack. Nuts are not included with this type of jack. You have to order them seperately.

Even if you used the TRS versions, the signals wouldn't be balanced, correct? Would it be possible to have the outputs balanced?

Thanks for your video Cyrax!
Is there any documentation/build-guide in that full kit included?

Cool, thanks. That's what I thought they were but I wasn't sure because of the extra holes

[Cyrax]

Not at the Moment, at the Moment I try to Buil a Page: https://sr909.de with some Infos and Documentations.
Steda has Support me in some Questions directly. The TR-909 Service Manual helps also.
The most is logical and stupid. Only the Connection between the PCBs was a littlest tricky. But for this I try to write the Documentation asap to the Page.

[crowhurst]

Excellent - thanks again!

Correct. Using TRS jacks would't change a thing. The ring holes are just not connected.

If you wanted a balanced main out you could use something like this:

you would need one balancing board per channel and it would require some trace cutting and wiring

Do you have any info about the DAC boards? what value resistors and do they deed to be .1% or something? Any pics of one assembled?
Thanks

[Cyrax]

This is a livestream from me about the SR-909


And when you give me the Number of the Resistors (You can found it in the Service Manual of the TR-909) then I can give you the Resistor Values. But you can download the BOM at https://sr909.de, there you can find all Values

[synthetek]

They are not in the BOM or service manual, The DAC arrays that need surface mount resistors RA1 , RA2 etc... they replace the RM-0621

[Cyrax]

Puh, i am not sure that I understand you correct. Here a Picture of the Mainboard that's stuffed with all components (without iC´s)

[synthetek]

These

[Cyrax]

Ah, ok, sorry, this Values I don't have :(
