BeoLab 8000 different PCB02 versions: schematics?

[KolfMAKER]

Having worked on a few BeoLab 8000’s, I noticed that the layout of PCB02 can be different between different serial numbers. Looking for info about this, I read somewhere that PCB02 has versions 01, 02, 03 and 04.

Question

1. Is this correct, and how can they be recognized? (If not correct, please explain)
2. I have only one service manual, with one version of schematics. Where can I find the schematics of all these different versions?

You are a silver member. Look at the service manual in the database of schematics, it already includes two schematics. one without ( date 11-1991) and one with ABL.( date 03-93 ) printed on de pages, including other PCB layout.

Furthermore what I have noticed, B&O works with alphabetical revision nummers printed on the PCB by changes, such as ‘PCB partnummer’  Rev N and also with version nummers with a number behind the PCB part number like ‘6142169(0) ~ ver 0’
