Unless the wiring at the solder side of the board was changed to suit (it doesn't look that way in your photo on the previous page), it will
most likely have killed one or two diodes in the rectifier, leaving it running only on the remaining.
I suggest you replace it. Check the connections at the backside and make sure to fit it right.

What Martin is telling you is that the new rectifier pin layout is different so you have to make sure you connect the pins to the right spot.
I think your original question may have been whether the new device is plug-n-play compatible with the old one?  The answer to that is that it is not.
Perhaps there was some confusion there.

Thank you both for clearing it up; good news is that I have not applied any power yet so I can remove it and switch the pins to their correct positions.

Hello 

Michael:

I've gotten all the answers I needed to date - just waiting for some extra items I ordered - COVID really mess everything up.

The service kits were supplied by Dillen and Beoparts (See earlier in this post).

You will get a complete set of Caps, trimmers and the secondary bridge req.

If you need other items, he will either guide you or supply them if they are available in his inventory.

I also got push buttons parts (speaker-1, loudness and filter) that needed replacing from him.

If you need expert help you can always post on the workbench forum; there are many experts who have been doing B&O repairs forever.

They helped me more that I could imagine.

Lots of luck.
