Could sommeone arranged a GB on this one?
I have not finnished my last GB yet, So I cant do another one now....🙂
Reichelt doesn't have a minimum on those parts. You can buy 1 and have it shipped. Took a while to get them delivered to the US—you should have faster service in the EU... Not sure a GB would be of benefit... Price is WAY cheaper than the Mouser versions—same brand—slightly different part numbers, go figure.
I have no problem with input boards that loosen over time. I use a "split washer" ......think the name is.....to apply pressure on a shim.
The "standoffs" I use to mount the input boards are female-female so I just use normal 3mm screws (no nuts 🙂 ) .....it also looks nicer 🙂
I had one complete M3 bolt, split washer under head, up from bottom of main board, +toothed lock washer, +fully threaded aluminum standoff, +another toothed washer, +daughter board, +toothed washer, +nut. For anyone interested... loosened over time at the connection to the main board—so, between standoff threads and toothed washer and main board and split washer, not the daughter boards, they stayed tight...Quite impossible to get a tool in between main board and heatsink... Dunno.... YMMV. Meper's solution sounds like it decouples the main board attachment arrangement from the daughter boards—I like this move. It's possible swapping boards plus heat cycles and a single threaded bolt for everything made the main board connection funky over time...

Strange......but will check next time I swap input boards.
I use chromed brass standoffs but probably not that makes the difference.
I use only flat washers and split washers to make the contact pressure.
Maybe if the star washer over time dive into the aluminium?
I did not want to make marks in my PCB's. That is my reason for not using star-washers 🙂 ....it seems the contact pressure applied by only split-washers on flat washers are ok. Sound is fantastic.....

M2X - BlackForestBuffer
Good evening M2X-builders,
I have exchanged the 330Ohm resistors on the rails to 270Ohm+33Ohm (in series). Both boards are running. Was this the issue? 😕
The boards are playing music. 😀

M2X - BlackForestBuffer
Good evening M2X-builders,
I have exchanged the 330Ohm/5W resistors on the rails to 270 Ohm+33 Ohm (in series = 303 Ohm). Both boards are running. Was this the issue? 😕
The BFB-boards are playing music. 😀

Hello Patrick,
after that short listen:
It sounds very detailed and 'fresh'. I have to add, that my M2X is running in my active system and it is 'only' driving the Mid/Tweeters.
Very promising...
Cheers

Good morning Meper,
yes, it is pretty dark in the Black Forest. Some areas are very sunny...
What makes the problem more difficult - I was born there.
Does this mean that my brain is black and dark😕
No light is switching on - the aha-effect?
Have a nice week!

BFB for M2X Gerber Files
Since this is now all working, here are the Gerber files as promised.
This version is slightly revised to give more space between components for soldering.
Circuit remains unchanged.
Happy soldering,
Patrick
