I have been collecting various Beosystem 5000 and 5500 components over the last few years when they would show up for sale with low values. One of my goals this year was to spend some time and get a working 5500 system so I thought now would be a good time.

So far I have a Beomaster 5500 recapped and working well. I also have a CD5500 that only required a belt change and a Beogram 5000 that I had to change out the transformer and fix the usual deck lid latch.
The Beocord 5500 is on my bench now but it looks like it will need a part or a repair of a part.

Here is the restored system so far. It looks nice on my SC60 cabinet and with a pair of RL140 speakers.

I have been using my BeoSystem 5500 for a week now and I am pleased with all of the components except the Beogram 5000.  The Beogram is exhibiting a noticeable variation in speed. I can hear the sound slow down and speed back up. Measuring the speed again with my digital tach I measured an upper limit speed of 133.9 RPM but a lower limit speed of 130.8 RPM.  I have a new belt from Martin installed in the Beogram so is the problem likely electrical?

Sure....although I didn't make a list.

On the Beomaster 5500 I went through and replaced all of the electrolytic capacitors with new ones. I restore quite a few B&O components so I already had most of the replacement capacitors already. When I don't have the correct replacement value I look up a new one and typically order one from Mouser, Newark or Digikey.  I always try Mouser first because they are located pretty near me so I can get the parts very quickly. 

When changing the electrolytic type capacitors I match the capacitance value and the voltage rating.

On the Beocord 5500 I only replaced the belts with new ones from Martin.

On the Beogram CD 5500 I replaced just the belt at first.  Later the CD 5500 started having a problem with its power supply and would suddenly shut off.
I replaced the electrolytic capacitors in the power supply circuit and it has been working great ever since.

Hope that helps,

Sure it helps!

I just dove in deep and can use all relevant info.

I have the same setup except for the CD.

It is still not vey clear to me if there is a big difference between the CD 50 that I have here and the 5500 :-)

The Beomaster is working , I am sure that recapping it will be the rewarding thing to finish up the project.

What difference did it make when you did yours?

The Beocord is waiting its upgrade kit to be recapped , I found a complete cérat set at Audio High Store. I will order the belts as well.  Is Martin the best placed for that?

If things turn out as I hope I will be doing the Beogram soon as well.

Beo greetings,

Hugo
