Here is the Beomaster 8000 that I acquired as part of an 8000 system earlier this year. I have been wanting to get this receiver working again but kept getting side-tracked. I think it is now time to dive into it. I have the service manual so I think I am set.

The first thing to figure out will be why the BM8000 always shows CLIPPING mode when it is turned on (STBY to any function). Tomorrow I will open the unit up and clean off the dust.

This will be a nice thread. Looking forward!

I have opened up the Beomaster 8000 to inspect what sort of work I have to do on it. Starting with the back, there is a fair amount of dust but I have seen a lot worse. Once I get it all open I will clean it up and see what capacitors I need. I have the original service manual and it will give me the values but I like to check what is actually on the boards.

The Beomaster 8000 is one of the heaviest receivers I have had to lift. I wonder how many of these units suffered damage because someone dropped them? Here is why they are so heavy. A giant of a transformer.

I took a quick inventory and checked it against the Beomaster 8000 service manual and boards. I think I have about half of the replacement electrolytic capacitors in my own stockpile.  They are extra audio grade capacitors that are less than a year old. For the other half I will probably have to make a run over to Mouser tomorrow or Thursday. I am thinking of leaving the microcomputer board alone as it requires un-soldering the metal box. It looks like there are a couple of electrolytic capacitors in there though (a 1uF and a 22uF) so maybe I should go ahead while I have the receiver open.
