I have a Beogram 4004 with a speed related speed issue. This problem came up 3 years ago and I purchased a new belt thinking that was the most like cause. Apparently not. New belt in place and I promptly forgot about this issue.

This 4004 has been my “trouble free” turntable having never once needed an adjustment. (a lot more than I can say about the 4000, 4002, AND 8000)

Playing a standard 33 1/3RPM record is exactly what should be expected.

However when playing a 45RPM LP record, the 4004 slows down mid-play to near stop, playing VERY, VERY slowly. Switching back and forth between 33 1/3 and 45 does little good. Towards the end of the record the 4004 always speeds back up, possibly even playing a bit too fast.

I applied pressure to the record during play to see if the belt slipped, but there was no evidence of that.

Changed the record to a standard 33 1/3 and problem solved…. but (of course) not really.

I am thinking perhaps a bad contact, but I really don’t know, I am guessing blind.

If anyone has experienced anything like this with a 4000 series turntable I’d appreciate a suggestion as to how to address it.

Thanks,

Jeff

Hi,

it's been a long time since I haven't been on this Forum. This problem rings a bell.. my Beogram 4002, type 5513 had the same problem. The culprit  on mine was the speed relay. It's the small plastic and transparent box under the main board, written Siemens on it (if I remember correctly) I think they tend to oxidize with time, making bad contact with the speed that is not used really often (45 rpm..), thus the speed fluctuation. I have desoldered it, opened it and gently rubbed it's connector with a piece of parchment paper soaked into deoxit. Problem solved.

Meanwhile, I bought a replacement from the nice guy who has the Beolover blog. However, I have never installed the replacement since the problem has never reoccured. But I'm conscious it probably will one day or another... 

Hope that help

Guillaume

I am happy to report back that cleaning the speed relay box solved the 45rpm stability issue.  I used a piece of paper with detox, and then pro gold to clean the contacts. Very happy now Big Smile Thanks again everyone for your advice.

@Piaf My 4004 does have 7 pins, so I am all set if/when I decide to take the 2400.2 plunge.  What speakers do you use?  I am interested in trying the Beolab but I know they won't work with the 2400 (at least not without some mods).

Excellent news! Mine didn't but Martin came to my rescue with the 2 additional pins.

You need a Beomaster 2400.2 to make it work. Although I hear the last of the 2400's were so equipped.

Here at BeoWorld the Beomaster 2400.2 is not entirely held in the highest regard (by some) as compared to the Beomaster 4400 or Beomaster 8000 but I can assure you, the Beomaster 2400.2 is a delightful amplifier and WELL worth the "plunge." I wouldn't be comfortable comparing them side by side, note for note, BUT I feel confident you will love the remote controlled Beogram 4004 along with the radio selections.

My 45 RPM issue disappear COMPLETELY with over 100 plays and NO problems. But thanks to YOU if/when the issue reoccurs, I know what to do to correct it. Thank you so much for this post!!!!!! Big Smile Big Smile Big Smile
