Martin, Then I will plan to replace these 8 transistors and see what happens. If memory serves, during my protracted purchase negotiations for this Beogram 4000, the NYC shop replaced the mother board. The fact that it worked well for nearly a year says the job was done correctly, but doesn’t give me the sense of security that I would like with

Martin, My current game plan it to tackle these transistors after I am finished with the big family birthday party coming up this weekend. However, it occurs to me that while I may well be able to replace these 8 transistors, there are numerous other components of questionable value, as I have no real knowledge of the motherboard’s history. Do

Thanks Peter, The 4500 CD player is an obvious match for my Beomaster 4500 and I could use the remote with it as it comes with the 7-pin DIN connection, unlike my CDX which has RCA plugs. (Works with my McIntosh setup, so the question is do I want a CD player with the 4500.) The Beogram 4500 is with a re-seller on eBay, not usually the best senerio

What is the major difference between a Beogram CDX and a Beogram 4500? I have a delightful CDX and have an opportunity to purchase a Beogram 4500 CD player. I note the difference in appearance as well as the 4500 is the newer of the two, but I’d like to know what to expect in the difference in basic use and performance. Thanks. Jeff

Sure thing. Everything about the Beogram 4000 is intimidating in the beginning, but once you get started, it really is not all that difficult. I will take a good look and let you know what I find. I am tied up with a major family gathering this weekend, but after that, I will give this matter the attention it deserves. Thank you again for ALL your help

Martin, Thank you for the excellent direction. I will see what I can do with these transistors. I would have no concerns about shipping the board, however if I find this project exceeds my ability, perhaps I could purchase a good H-bridge from you and then send my defective one back as an exchange… if that is how this sort of thing works. Jeff

Thank you Martin for your valued and learned advice. On the home page of the forum section it states that “there are no stupid questions,” with that thought in mind I hope you will allow me to ask what well may BE a stupid question. The first time the fuse blew was with the tonearm midway through playing a record, so I assume you are thinking

Thanks Martin, I am looking for a bit of direction. This Beogram 4000 has performed very well for 10 months until it blew a fuse mid way through playing a record. With the fuse replaced, the 4000 platter turns, the arms go to the correct play position and begin to drop. But then something very odd happens, instead of dropping completely to the record

I am sure you are right, however today, for the first time, the light came back on in the sensor arm. Jeff

What is the correct fuse value for the power supply on a Beogram 4000? If I am reading the manual correctly it is part 6600000. I am using two 250ma 250 volt buss fuses and have been told that the correct fuse is a 300ma 250 volt. Which is correct for a Beogram 4000? Jeff
