The Meridian 506.24 is a seriously good CD player, one of the very best I’ve had the pleasure of listening to. This 506, however, had a strange, mystery fault. Read on to discover how I serviced and finally fixed this stunning CD player.
If you want a smooth, relaxed, organic-sounding player, you’ll go a long way to find one better than a Meridian 506.24. Meridian really were on a roll when they produced the 506, 507 and 508 series of CD players, from the mid-nineties. All are superb players, easily beating most players even now, despite what you might think.
In fact, I like the 506 so much that this unit has become my reference CD player. The only thing I need is a matching Meridian remote – anyone maybe have an unused remote lying around…?

Plenty has been written about just how good the 506 series sounds, especially the 506.24. This TNT review is a good starting point. If you want a few more technical details, revision history and owner’s manuals, check out the very useful Meridian-Audio Info page about the 506.
I’ll review the 506 in an upcoming piece. In this article, I’ll outline the original service and repair work I did to the player, laser replacement, the unit’s mystery fault, and finally, the moment I uncovered the underlying fault that lay dormant in this 506.24 for many years!
Standard Service – The Mystery Begins…
This 506.24 came to me for service last year, exhibiting a fairly common fault with the loading mechanism. I repaired the fault with the loader and serviced the player, all fairly standard stuff, requiring no major surgery.






So, with the loader serviced, everything cleaned and lubed and back together, I plugged the player in, hoping for a smooth running drawer. The drawer did indeed now work perfectly, but the player would not read a disc. WTF..?
Extended Repair – New Laser/Mech
My testing of this 506.24 showed that the spindle motor wasn’t working properly. It seemed to be getting power, but not spinning. All CD players eventually need replacement lasers. Laser power output drops over time. Eventually, power output will drop to a point where the energy reflected off the disc is no longer enough to enable correct focus and tracking. Sometimes spindle motors also fail and, based on the symptoms, that seemed to be the case here.
The 506 was manufactured with two different Philips laser mechs. This unit uses a VAM 1205, but others seem to use a CDM 12.4. I have a supplier of both CDM 12.4 and VAM 1205 mechs. Much has been written about these mechs and there is much much misunderstanding about them. They are NOT interchangeable. The VAM 1205 has a hall-effect motor, whilst the CDM 12.4 uses a standard DC motor. You have to use the right part for the player in question.
Anyway, I chatted with the customer and explained the situation. Obviously, this deeper fault had to be repaired and this would take a new mech and possibly a bit more troubleshooting. I felt that this was worth doing, but the owner just didn’t want to proceed any further. Instead, he very kindly offered to donate the unit to me, as project or for parts. Thanks again Jed, your donation is genuinely appreciated.
Some months later, I replaced the laser/mech, not sure if this would fix the problem.





The Ah-Ha moment!
So, with the 506.24 serviced, months having passed and now with a new mech installed, you can imagine my anticipation about finally testing her. I carefully put everything back together, not a trivial exercise, inserted a test disc and hit play… Nothing. The player was still dead. Not happy.
This 506 obviously contained a fundamental flaw that was preventing her from running. Further testing now showed that the spindle motor was getting intermittent power, but why? I spent several hours going over the drive and control board.
Finally, after much time spent tracing power and other circuits, I found it. It’s evident in the image below, I wonder if you can see it?

Resolution – Final Fix of the 506
So, I found my smoking gun. A very dry joint in the mech power supply causing an intermittent break in power to the motor. This fault had obviously been there a very long time. The joint would have been barely adequate when manufactured, and then gradually deteriorated over time to the point where simply moving the player would have caused it to fail.
In other words, simply delivering the player to me, was probably all that it took to finally break the joint completely. Once broken, the player could never read a disc again, until I repaired this tiny, hard to find fault. I wonder how many Meridian 506s were scrapped because of a fault like this?
Finally, I’d found and fixed the fault that accounted for the intermittent symptoms and other weird effects I’d observed. I reflowed the joint and the player sprang back to life, working perfectly from then on.


This wonderful Meridian 506.24 CD player plays on as part of my system, for now.
I’d be very happy to service or repair your Meridian 506, 507 or 508. Get in touch to start the conversation!
Hi, I Once owned the 506 Fantastic player, Also had the 586 dvd/cd player and was able to compare directly. The 586 was even better.My 586 has hardly been used so laser should be great but it has an issue where the display and control buttons stop working. Cd will continue playing tho. I am considering repairing this fault. Mine is the mark 1 and in the mark2 they installed a fan. Could it be overheating? Any thoughts?
Hi Craig and thanks for your comment. Which 506 did you have? The 24 is better than either of the two previous 506 iterations. In terms of your 586, I would need the unit in for a proper inspection to be able to offer any really useful advice on this. Are you a Perth local?
Update: I opened up the 586 dvd/cd player reseated a few connectors in there and seems to have fixed the display/ remote problem. I wish I had of tried that years ago. All the best Craig.
Hi Craig, great news! Depending on the fault this is sometimes (through rarely) all that’s needed. Glad she is up and running again.
Hi, I am in Victoria but I would consider posting it.
That’s tricky, I generally prefer to deal in person with customers and the shipping element can create problems and certainly adds to the expense.
I had the 506 -20 and I still have the 563 dac.
Ah yes, the 24 is better again than the 20.
Yes of course, i am going to get it out and play it a while to see exactly what its doing as its been stored for a while now.
hi what diameter and shape drive belt did you use? Also, in mine there’s a spring which seems to have lengthened – the drive “bumps” when it closes. – any suggestions for a replacement spring??
Hi Ciaran, I don’t give out specific data on belts and things but I always use an exact replacement for the original. Regarding tray operation, check the open and closed positional microswitches, they can be slightly adjusted in most cases. The spring might be worn and of course I have a range of springs, belts and thousands of other parts here but I’d need to match them as they don’t provide details of any mechanical parts in the service manual. Try standard commercial suppliers like Farnell/Element14, RS, Mouser etc for springs, they sell sets and individually.
