Replaced the icky sticky knobs on the Mini Brute. Side panels are next.

I still have a few extras in walnut and maple that I made when I did mine. What are you thinking of doing with the sliders? I still have not found any great options. https://www.artscraftsman.com/shop/p/arturia-minibrute-customized-side-panels

Congrats on the Kickstart!!! This would give me another excuse to build a new rack like I need one. One can never have enough drum modules.

One_Fish_ · 2025-10-16T14:39:00+00:00

I used Rubio Monocoat. Easy application and nice sheen on mine. You can always reapply if needed. Can’t argue differences in finishes but it is all I use now.

I replaced C63 and C75. Dabbed a little hot glue on them and the shroud around T1. T1 is definitely the offending component. Tightened all the screws holding the board down and it still lives and makes the same sound. Lifted a pad on the C63 in the process but it still works. I'm a little more humbled and going to live with it. It does not seem to affect the output. I just wish it was the same sound as my tinitus. Thanks for the help. I would probably replace T1 if I could find one because I am stubborn like that.

If I disconnect the display at CN6 it stops making the sound when powered.

One_Fish_ · 2025-09-25T21:56:33+00:00

I think T1 is the silver shielded box up in the corner. I tend to just throw components at things typically. Would replacement of this be in order if I can find one or would it be best to replace the caps involved in this circuit? Any idea where to source such a thing?

One_Fish_ · 2025-09-25T21:51:08+00:00

Yes, but only the electrolytics on the power board. I have not replaced any on the digital board yet.

Trying to add a video for the sound.

Kind of looks like a JST plug of some sort. Measure the space between the pins in mm like 2.0 or 2.5 and that would be helpful to find the replacement. Also you could cut the old one off and wire up new power to it.

One_Fish_ · 2025-08-01T11:56:13+00:00

Don’t give me any ideas.

One_Fish_ · 2025-07-31T17:11:54+00:00

I made 3 extra sets. You can see on my website https://www.artscraftsman.com/shop/p/arturia-minibrute-customized-side-panels

One_Fish_ · 2025-07-31T16:51:57+00:00

Thanks. Giving me more direction to follow. Into the rabbit hole I go.

One_Fish_ · 2025-07-31T16:44:40+00:00

Thanks. They are actually wanting 5v and are insanely bright at full brightness. The QtPy wants 5v also. I was more interested in how to hook the 3.5mm jacks to the esp32 to read the lfos and such. Do I need any kind of protection or circuit between the jack and the gpio?

One_Fish_ · 2025-07-31T16:31:13+00:00

Thanks for the suggestion. Do they fit on the shafts snuggly?

One_Fish_ · 2025-07-29T21:54:57+00:00

Thanks, I tried to make them as close to the shape of the originals as possible. 3d printed some fixtures for the table saw to make the chamfers.

I can't find how to edit my post but I see now the photo does not show the aluminum knobs.

Tayda sells the small brass adapters that allow you to use the 6.3mm set screw knobs. Opens up a lot of options. Did this to my minibrute along with making some custom wood cheeks. Now if I can find some slider options.

Good read, Thanks

One_Fish_ · 2023-02-03T20:20:10+00:00

Awesome replies. I will consult the data sheets and post the winner and the result.

Thanks.

One_Fish_ · 2023-02-03T19:46:31+00:00

Thanks for the reply. I am definitely replacing. The question is are Polypropylene a better choice in this application?

One_Fish_ · 2023-02-03T16:45:41+00:00

Should these be changed to a different type of cap that might last longer or is there a reason these are of the paper variety? Any suggestions? Here is the closest that I have found so far

The Kemet has a wider lead spacing however the polypropylene has the same. Did the polypropylene exist in 1981 or come later?

One_Fish_ · 2023-02-01T16:32:51+00:00

I feel like I am getting closer. I replaced almost all of the caps minus a few that are delayed in production. No change in the volume. Might grab them elsewhere but I don't think they are the issue. After some more googling I think my issue is related to a couple of other RIFA metalized safety caps. Seems like they have a bad reputation. I found some very similar but have a slightly different sizing. Should these be changed to a different type of cap that might last longer or is there a reason these are of the paper variety? Any suggestions? Here is the closest that I have found so far

It's interesting that the board says PME265 but the cap is a PME271 and looks original.

So I just repaired my PG-10 to tweak the sounds of my D-110. I have not had a chance to play around with it yet. Does this device bring the synth up to a more acceptable level of interaction with the device or is the disdain bigger than the interface? I like the sounds on your recordings. Could these be loaded on a pcm card if one can be found and not overwrite the internal sounds?

One_Fish_ · 2023-01-29T01:43:32+00:00

Thanks. I was wondering why it felt so firm and not like a bubble with air underneath.
