Hi all
Manufacturing process is now running. I will post a link here to my ebay when the boards are ready for purchase and you will be able to buy them from there.

We have to settle with the best layout board and I agree with you that the later ones are better to work with. No need to remove the components if you send the unit to me, I would like to see which components that are fitted in some places if I would need that information.

Fredrik,Excellent news! For the processor boards, how are you going to manage the casing?Salvaging the old covers is probably not a good idea.Does the processor board even need the shielding can? I’ve had my 8000’s running without it with no issues.What B&O came up with wasn’t the best part of this otherwise wonderful receiver...

Thanx 👍
I have not been thinking about the shield box at this stage. I will see what is possible to do with it when I am working with the layout of the pcb. Imagine if we have new pcb:s for this and use a similar solution of the shield box as in the later versions, would we really need to remove more than the top cover of the shield for examination?
I would recommend to use the shield box. The CPU can be quite noisy and sometimes be heard at higher volume settings. The routing of cables from the CPU is very important too and it should not be mixed with signal cables if possible. It is also the opposite to not let the CPU module get disturbed by external interference.
I think b&o had to cut costs here and there although this was a flagship back in the days. There are a lot of compromises in the BM 8000 for example the PCBs and usage of cheap components (capacitors, trimmers, potentiometers, switches, connectors etc.) that could be of better quality.

Superb!
I’ll order a set in a few days.
👍🏻👍🏻👍🏻
Seems ridiculously cheap to me! Thank you for doing this as will keep a number of these behemoths going!

Hi Guys
Thank you all for your orders!
Shipping is now in progress, so you will hopefully receive your PCBs soon. Happy soldering :)
I want to point out a misprinting on two diodes D201 and D202 on the power amplifier boards. This misprint originates from B&O original PCBs. I will correct this in future versions of this PCB. The diodes shall be mounted in the opposite direction showed on the printing, see picture below. There is also a reminder of this in your parcels.

Noted...Thanks

Hi Fredrik,
The boards arrived safely today.
I won't be able to get to them for about three weeks but looking at them makes we want to get started. I keep an opened up, working Beomaster 8000 in my workshop so that is the unit I will use to test them. I'll let you know when I am ready to try them out.
Thanks!
John
