Thanks for the order!
The Build-Document works fine to download here, what kind of problem are you having?

Here is a temporary dropbox link if that helps:

i cannot download from my smartphone (Galaxy S4 with chrome) the buildersguide, mabye because your website SSL certificate isn`t correct installed - globalsign nv-sa.
have you missed to installed the root CA from globalsign ?
https://support.globalsign.com/customer ... rtificates

in firefox works the download, but please check your SSL config.

EDIT: chrome dont have globalsigns root ca in his browser "keystore", its needed to add the globalsign root CA in the webserver "keystore".

Thanks guys. :)

I've been in contact with my hostprovider, who also handles my SSL. They say it's all working like it should, but there might be older browsers where these mentioned things might happen. Should cover 97% of the browsers and configurations however.

Feel free to PM if you're having any more trouble.

I have just ordered some of these for the build: (I blooming well hope I got the right ones! :doh: )

http://www.micross.com/pdf/LSM_2N3958_TO-71.pdf

I had to order 10 because of their stupid minimum order levels, and as I will only need 2 I can send some out to wigglers at cost if they like.

Let me know.

I'd be up for that - up for any others too if you come up against any other limits (I'm not going to be onto building this for at least a month or so, so will gladly snap up any extras if it make sense for you!)

Oh, i forgot to add a note in the Build-Document that the layouts in there are for reference. The boards themselves have the values printed on them. :)

Will update the Build-Doc asap.

I received ten 2N3958 TO-71 from Micross this morning, I only need 4, so I am more than happy to send the spares to fellow wigglers at cost.

Let me know,

Simon.

Have finished the great Arp filter today.
it sounds better as arp4072 yusynth design filter.
It works great on 15v with a bridechamber arp4072 panel,
The finetune knob is placed on pcb, i dont need them.
its sounds like a ttsh filter.. wonderful

Got mine, thanks :)

May sound an obvious question but can anyone tell me what orientation the pcbs should be? Obviously the control pcb has the pots and jacks on the side of the writing which then goes to the back of the panel. But is the other pcb in the same orientation e.g. the white writing pointing towards the back of the panel.

Hope that makes sense. Probably a really obvious answer but I don't want to get it wrong.

Thats a good question i realize i overlooked in the Build-Doc!
As it would be almost impossible to do the Trimming with the components facing inwards, the Core-PCB should be faced outwards.

Like in this image:
https://www.dropbox.com/s/6245jslrcjkw2 ... k.jpg?dl=0

(never mind the oddities in the pic, its from the prototype)

So in other words, the PCB's should be back to back.

Panels and PCBs arrived safely here this afternoon, and they look very good indeed. :tu:

I have to admit that I was sceptical about the new typeface, as I already have 5 of your modules in the old style, but I must say that the new ones really look very sharp indeed. It is a clean, clear and purposeful design. Thank you.

Ok, finished tonight but unfortunately I haven't got it working. Not sure what I've done but (I know it's difficult) any help would be appreciated.

Basically got to the calibration part and no matter what I do it's always outputting 100Hz, changing the trim pot R164 makes no difference and nor does changing any of the others for that matter.

Any ideas?
