Hi there, I'm new to the forum but have been a vintage B&O lover for years. I'm about to dump the RAM in my 6500 due to a couple of very loud radio alarms that keep waking me up at night. I've tried everything but I guess my MCP isn't the correct remote. I opened my Amp and found this wire poking up which is coming from the FM antenna input. I would really appreciate if someone can tell me where it belongs and how to put it back.

Thanks in advance for your help.
Also I need a cap kit for my S120s if someone can point me in the right direction would greatly appreciate it.

There should be a socket for that cable on the tuner PCB (the one you have flipped up), near the metal can containing the FM frontend. It’s not visible in your picture. Just plug the cable back in.
For cap kits, contact member Dillen. And welcome!
EDIT: the socket should be right at edge of the PCB, between the metal can and the hinge bracket.

Thanks so much, I was able to get things back in order. I also put it in test mode, dumped the RAM and ran through all of the tests. This one is a keeper, I burned up my last one, not sure how it happened but I openly blame my wife because we're the only two in the house and she keeps reminding me that I can never be in the wrong.
Now I just need to adjust my turntable and then make one good tape deck out of two.
Thanks again for the quick response and helping me get back up and running.
Cheers
Another question, I plugged everything into my BM6500 and I'm hearing a slight when I change cd tracks or when I change volume. Is this fixable for a DIYer?
Thanks
It’s the digital communications bleeding over to audio. Pretty much normal, unless it’s disturbingly loud. Then it could be some internal cables routed incorrectly, loose ground connection somewhere or even bad speaker cables.
Bad decoupling of the low voltage power supplies.Allowing noise from the digital control of the volume and tonecontrol settings onto the supply rail for the preamplifier circuits.Replace the decoupling capacitors.

Thank you, that was a very crisp answer. Would this cause i to sound a little bit 'dirty'? It sounds a tad bit less clear than my old amp.

Yes.That and the electrolytic capacitors in the preamp and output stages.
Interesting input on the data transmission noise leakage. Both my 5500, and 6500 have this phenomenon, barely noticeable but its there!
I bought both sets brand new, and always assumed it was down to a less than ideal ground scheme, perhaps I should give the decoupling a bit of attention?
