Having tough time identifying wires on Beomaster 3000.2 Type 2402.

20 replies

Hello. I am replacing the big capacitors on my receiver and due to my stupidity 25 years ago when I removed two of the caps in an attempt to find replacements, I left the groups of wires disconnected and unidentified thinking it was just going to be  afew days before I had the caps and re-wired it up.

Fast forward 25 years and I have the caps and the desire to get it going again with my beogram 4004 and B&O rosewood table arriving last week, and now I am absolutely paralyzed with fear on connecting the wires again.

I downloaded the schematcis and I have been pouring over them for a few hours comparing the tiny, tiny drawings with what I can follwo on the circuit and I am afraid I am getting myself lost and frustrated.

Does anyone have a picture of the wiring of the 3 main caps?

The wires are grouped together in sets of 5 or 6 wires each and I thought it would be easy to figure the neg from pos but it looks like B&O does not adhere to a strict policy of black and red for neg and pos. So I have a group of wires that have red and orange, and white&Red, together with a white& black and white&grey. And I have a set with black wires but it also has white& black in it's group.

If I had a color picture looking down on the terminals of those caps, I know I could confidently attach them to the correct posts, but without it I may go blind trying to read the old schematic with a magnifying glass.

 

Thank-you for any feedback on this!

 

Does this help?

 

Dan,

Upon further review of your post...

I think you want a pic "looking up" w/ the base plate removed... to see the bottom of the caps. Correct?

If you give me ~2 hours I can get the pic you need (w/ a better camera too).

I will simply replace the one above.

Please advise... I am happy to help!

YES! You are correct Sir!

I need the opposite view from bottom with base removed.

I am VERY impressed and excited to have gotten a response so soon.

I have the unit on my desk all open and ready to assemble and the new beogram 4004 will be here in the next two hours so I am very excited to see the picture.

Thank-you again for taking the time to do this for me.

Photo updated.

I will leave the BM open if you want/need any more shots!

Have fun! 🙂

Fantastic job!

I see 90% of what I needed.

If you still have the BM open, can you tell me where the black wire which is attached to the pos of the center (larger grey cap) goes to? That one black wire attached along with the red ones to that terminal is a bit confusing becasue I have several black wires and still can not decide which one that one is.

There is also the issue of your BM being different enough from mine that the exact number and location of wires is different. You have a PC board in the pic (ending in 40401) that I do not have in mine.

My BM is 300-2 Type 2402. But still, there is enough of what does match, that I am comfortable.

BTW - The Beogram 4004 just arrived as well. Thanks so much for your time!

Dan,

Mine is a 3000-2 2405...

The black wire in question runs to the board in question... 40401

I really appreciate the effort you made to remove the bottom plate and take the pictures for me.

With the difference in our models I am still stuck with identifying a couple of black wires that may or may not be pos or neg and also may or may not be power cap but instead be output cap.

I am stuck with undoing the lacing from the wiring and tracking the source of each wire individually and checking it against the schematic.

]This may take a week to get through.

If anyone else has a 3000-2 Type 2402 like I do, would you be willing to take a picture of the terminal side of your three caps and show where they terminate in the case of the few of them that terminate to the resistor PC board right next to the terminals (not seen in burantek's pic because of difference in model types)?

Cracked open my 3000-2 2402 for you - hope this helps:

 

 

Sonk... 🤒

I love this site... 😳

Hopefully your pic will get Dan's BM on the mend!
