    Thank you all for your replies, much appreciated!

    Thanks for putting the manual up Multicare, It’s a much better copy than the one I found but it still doesn’t have all the pages, I’ve come now to realise with model number changes B&O only issue the pages that have changed. The 7000 is in some respects an upgrade to the 6500 so for the power supply circuit for the 7000 you need to look at the 6500, that’s my best understanding at the moment.

    Anyhow back to the 7000.

    The 12v rail is at 39v and the -12v rail is at -30v. C5 on the AM RF amp board blew up and I wonder what else has been killed. PCB2 is darkish brown in the area of R34 and D7 & D8 are corroded.

    A drawing of PCB 2 would be useful.
