Beogram - how do they stand up now
in BeoGram · May 2, 2019 11:14True, a turntable consists of a chain of components but you can still compare with another chain of Components (turntable/arm/cartridge/RIAA).
Beogram - how do they stand up now
in BeoGram · May 2, 2019 06:43I have four different Beogram, 5500, 6500, 4002 and 6000. So far, I have only been using the 5500 and 6500, both with MMC2. I am surprised buy the noise pickup from the vinyl. These are not up to my conventional turntabl…
Beogram 6500 Issues
in BeoGram · Jan 24, 2019 07:09I also think the need for lubrication is a must. There is a section in the service manual pointing out how. The cartridge need more than 1 gram to track correctly. The MMC-2 I have from www.tonabnehmerservice.de have a r…

Occasional speed variations on Beogram 6500
in BeoGram · Dec 10, 2018 06:17I have tried both turntables in various chains, three different RIAA stages for instance, two differnet replay devices. Tracking force is checked and I have tried different settings. I have also tried the turntables in d…
Occasional speed variations on Beogram 6500
in BeoGram · Dec 9, 2018 17:52Fitted new drive belts (platter and arm) and now it is running without speed variations. Still, both my 6500 and my 5500 with on outboard RIAA, give a rough sound. Both have restored cartridges, sapphire cantilever and f…
Occasional speed variations on Beogram 6500
in BeoGram · Nov 23, 2018 17:28Yes, I know the process Beolover uses.That is a process above my capabilities. Beolover charges $ 80 for the infusion. I plan to send my 4002 or 6000 to Beolover for a complete overhaul. I will pull out my Beogram 5500 a…
Occasional speed variations on Beogram 6500
in BeoGram · Nov 23, 2018 07:35Dillen, what kind of oil should I use for the motor bearings? I have some oil for capstans of Studer/Revox tape recorders. It is a "Sinterlageröl". Can that be a good choice for the motor too? Roger
Occasional speed variations on Beogram 6500
in BeoGram · Nov 21, 2018 18:55Yes, I know that the motor barings can dry-out. The spindle bearing is dry. I have another Beogram, a 5500 that I will try too. Just like the 6500 because of its built-in RIAA (re-capped with many film capacitors). I hav…
Occasional speed variations on Beogram 6500
in BeoGram · Nov 21, 2018 17:55I have some strange speed variations on a Beogram 6500. New belts are new. This happens about one time per side of a LP-record. What should I look for? Should there be any oil in the main bearing?
Recaping Beogram 5500 and 6500
in BeoGram · Nov 11, 2018 19:05They are 30 years old and at least one is blown. Electrolytics use to dry out. In the RIAA-stges of the 6500 there are more of them that need replacement. Some of them are even in series with the signal and it can lift t…
Recaping Beogram 5500 and 6500

Re-fiting the top plate
in BeoGram · Oct 22, 2018 06:31I finally got it in place. Some violence helped... Another problem arised, the sliding cover does not hold on one side. As it will go into storage, I will not bother now.
Re-fiting the top plate
in BeoGram · Oct 21, 2018 16:20I have a problem with re-fiting the top plate on my Beogram 6000. One of the supporting pins is too high. I have not done anything to the deck except removed the top plate. What is the right procedure? https://www.dropbo…

BeoGram 6000 Quad
in BeoGram · Sept 5, 2018 06:18Yes, I know that and I have had some conversations with him. The one that he have is made for the later 4002 (type 5513), not for the type 5501 or 6000 type 5502. It will need to be modified to fit. Not sure about its so…
BeoGram 6000 Quad
in BeoGram · Sept 4, 2018 13:56I have both of them, one 6000 and one 4002. They are almost identical. Sure, the CD4 PCB is missing in the 4002. I liked the idea of having an onboard RIAA-stage but i am not sure it is a very good one. Started to look f…

Beogram 5500 and 6500
in BeoGram · Oct 2, 2017 07:08Still unclear how the drive of the tone arm is detected. From where does it get a signal to move?
Beogram 5500 and 6500
in BeoGram · Oct 1, 2017 15:56So the detection for controling the drive is in the arm sledge or elsewhere?
