There's a lot of OpAmps in there and they are practically all in the signal path. I also tried the OPA2134 OpAmp swap but came to the same conclusion, you did. It sounded great at first but I got tired of listening to it and ended up putting the old ones back. I think the sound got too sterile for my liking. I enjoy the original warm, soft yet powerful

For the Beomaster 5000, yes. For the MCP 5000, I don't think so but one can be put together if needed. Martin

No, If the relays click one after the other with a few tenths of a second between, that part is working. If they release again soon after, something is wrong in the amplifier(s). Could be a too high idle current or badly adjusted DC offset (or something else). Try measuring the +/- 55V and see if it is supplied to the amplifiers at all. If so, then

A matter of taste, I suppose, and this one, I'm afraid, is not to mine. The Beolab 4000 came in alu (or silver) too, if I remember correctly. Martin

It's actually very common to hear the volume steps and it's one of the weak points in the BM8000. Imagine a sine wave and then introduce a sudden change in volume. Depending on where on the waveform the volume change happens, it will break the waves continuity and the resulting flank will be amplified and if it happens at a fairly high volume

Nice job, I agree. Worth checking the 1,5Kohm resistor that sits right next to the cap with the severed pin on the stereo decoder. It looks chipped but may still be OK. Martin

As far as I know, the same two types of tapedecks are used throughout this whole series of Beocenters. Both are fairly good decks with identical specs. The same goes for the different CD decks used and I am also almost sure that none of these decks are available from anywhere anylonger, good thing being that they are mostly repairable. Martin

Dave, If it fails, you will have lost a wonderful 1970's design icon and a nice radio but you won't fail. You have a PM (check your inbox at the extreme top right corner of this page). Martin

The Beomaster 8000 is a wonderful machine but not the easiest to repair. Even experienced tech guys develop grey hairs occasionally. The service manual is download'able from our main site at a small fee - well worth it for all the info kept in there and this site will be happy to see some support. That manual would tell you that TE3 is a defect

LDR stands for Light Dependent Resistor. It's resistance varies according to the light that shines on it. Inside the Beomaster 1900/2400, a tiny closed casing contains a lamp surrounded by four LDR's. The volume control circuit changes the light output from the lamp which in turn changes the resistance of the LDR's. Two of the LDR's
