Been trawling the forum and found the following information so far.

Required for the amp board of each speaker - so will need to x2 everything:

2x 3u3 400V Supersound
5x 10uF 50V
4x 100uF 50V
2x 1000uF 16V

I've seen mention of using Nichicon FG and also Panasonic FR capacitors.

Anyone used anything different, such as the Nichicon KZ which is supposedly a 'better' series than the FG? Suggestions as to where to order from.

Also has anyone recapped the other capacitors such as the large power supply ones or the ones in the DSP/Comms/Signal section? Parts list?

Decided to go with the Nichicon Fine Golds. I've now completed the re-cap of the amp section and replacement of the resistors (just in time as well). The improvement was so good compared to the cost of the components (approx £50) and the 2 hours it took, that I'm now investigating the other capacitors in the speakers.

My speakers were manufactured in 1994.

This leaves the DSP electronics, although I suspect the gains here will be marginal, signal input board capacitors, and the PSU board capacitors. It is the latter that I a struggling with the most to find replacements.

They are 4700uF 63V Slit Foil (ALT20S 1040 CD)

Anyone have any clue where to source alternatives?

Thanks for the information. I had stumbled across that page and thought the 2T Slit foil would be good. However I could not find it for sale anywhere as a 4700uF 63V only the 10000uF was available.

Looks like DNM and BHC were used for the original parts. BHC are now a part of Kemet. DNM seem to be working with Supertech.

Kemet came up with the part number ALT20A472CD063 but again no retail outlets have it.

I have gone for the 4700uF 63V Gold Tune Type III capacitors.

If anyone wants any help, send me a message.

I've learnt a lot by doing them and will post a complete list of parts soon and a perception of improvement as I also put in new tweeters.

In addition to the amps, I've now done the rest of the capacitors including the PSU capacitors, the input board, and the DSP board and even the one in the display!

As promised here is a complete breakdown of the parts to service a single DSP5000 (don't forget to double quantities for a pair). I serviced a pair of 7 segment 24/96 upgraded speakers, so yours may be different. Its not difficult to open the backs and check the component values.

     Board   Qty Ea  Value           Manufacturer Part No

     Amp     2       1000uF 16V      Nichicon     UFG1C102MHM
             4       100uF 63V       Nichicon     UFG1J101MPM
             5       10uF 50V        Nichicon     UFG1H100MDM
             2       3.3uF 400V      Ansar        Supersound
             1       680R 5W         Kiwame       n/a
             1       330R 5W         Kiwame       n/a

     DSP     1       2.2uF 400V      Ansar        Supersound
             4       3300uF 6.3V     Nichicon     UFG0J332MHM
             2       2200uF 16V      Nichicon     UFG1C222MHM
             2       1000uF 16V      Nichicon     UFG1C102MHM
             1       1000uF 10V      Nichicon     UFG1A102MHM
             1       1000uF 6.3V     Nichicon     UFG0J102MPM
             2       100uF 10V       Nichicon     UFG1A101MDM
             3       10uF 50V        Nichicon     UFG1H100MDM

     Signal  2       4700uF 25V      Nichicon     UKW1E472MHD

     PSU     2       4700uF 63V      Nichicon     LKG1J472MESCCK

     Display 1       47uF 16V        Nichicon     UFG1C470MEM


Some of the capacitors are a larger physical size than the originals, but they do fit.

I got the most improvement from recapping the amp board. There was a very small benefit from doing the other boards, although it does protect against damage due to component failure.

With respect to the tweeter upgrade, this made little or no difference in my case.

Really surprised to hear about the tweeters, I've found that replacement is a great upgrade (using black domed tweeters, second hand). This means the original tweeters were fine then? How old were they out of curiosity? You couldn't return the new ones to the friendly Meridian partner then?

I think the speakers were originally manufactured around 1994 although not sure as I bought them 2nd hand.

I would not expect a PP to take back what are now used tweeters. I can only conclude that the original pair were still ok.

At least I have a spare set now.

In the parts list post I stated that in the amp section there were 5x 10uF 50V capacitors.

It looks like the voltage rating can vary as the pair I am doing at the moment has 5x 10uf 63V capacitors.

Not sure why they would be different, but I am changing like for like.

Before ordering components I would advise checking what you need by popping off the back first.

I finally made some time to fix my pair of 'beater' DSP5000s. We are having a party next month, and I thought it would be great to see if I can fix these and put them outside to play music. These were old speakers that were 24/96 upgraded from the 18-bit versions and developed some noise from the tweeter that got progressively worse with time shortly after I got them. Based on feedback from others, I suspected the amps needed servicing.

Special thanks to Tarik and Tyrone on here for some pointers along the way when working on DSP5000s. It was my first time recapping a speaker amp board. I successfully replaced all of the capacitors and did the load resistors as well. I did not see any bulging caps, but could see some discoloration on a few and the load resistors were badly burned (as expected).

The difference is night and day- the noise and warbling from the tweeter is gone and they went from my worse sounding pair of 5000s to my best. I am so impressed with the clarity and sonics, I think I will replace the caps on the amp boards of my Smiley DSP5000s. I used Nichicon golds or ultra fine golds and went with Supersounds per this thread. I am noticing the biggest difference in the highs, but overall they really sound amazing! It is actually hard to believe they are the same speakers.

The difference has me wondering how much improvement I would get from refreshing the DSP6000s? Similarly, I have an old pair of DSP6000s (probably from the early or mid-1990s) that were upgraded to 24/96. There is nothing wrong with them and they sound fine, but I wonder if there is any improvement to be gained by refreshing them. Has anyone taken on the DSP6000s?

I've re-capped a number of DSP5500's and DSP6000's with excellent results.

The process is very similar to that of the DSP5000's...
All the capacitors need to be changed (some 38 capacitors!), check the resistors (but they're normally OK)
There are two separate amplifier boards, four large power smoothing capacitors, and a smaller power supply board.

Drop me a PM and I'll send through a list of components. It's not cheap, especially if you replace the four large smoothing capacitors but there is certainly a noticeable improvement in sound.

Cheers,
Steve

Hi all,

If anyone feels they don't want to take on this kind of work on themselves, feel free to drop me a pm on here, or use the Contact Us section on our website. We would be happy to discuss any requirements with you.

Just so you are aware, apart from offering a full re-cap/service for DSP5000's, I'm currently doing the same service on my second pair of D600's.... in a month!!

Thanks

Russ

I upgraded all of the capacitors on the amp boards and PSU board of my 24/96 DSP6000s. In short, I cannot believe the difference in sound quality from the new caps! Major improvement in the midrange and bass. It looks like my set was from the mid-1990's with 1995 stamped on a few boards, so they were already old when I got them. It is incredible the level of detail and clarity that these speakers are capable of. I always thought the DSP6000s were exceptional, but there is a whole new level of performance unlocked with fresh caps!

The entire process including opening up the speakers and labeling everything and getting them back together took me about 9h spread over two days, and was about $60 in parts. As it was my first time working on the 6000s, I took my time with everything, but it is without a doubt the best improvement 'bang for the buck' I have done in audio. The caps are bit tighter on the 6000s than the 5000s in a few places on the boards, so I had to watch my dimensions on the replacements. My 6000s had all Rubycon caps (the light blue colored ones) which I replaced with Panasonic or Nichicon caps. Special thanks to Steve for some advice and guidance on the process since he has done several speakers with these boards already.

I would recommend to anyone with older DSPs to consider having the capacitors replaced on the amps. It made such a difference for both my DSP5000s and DSP6000s, and I would have loved to have known about this years ago. If you are not comfortable with a soldering iron, it is worth sending out to someone who will do this service for you. I have another pair of DSP5000s in my living room system that are next on the list.

I would like to recap my smileys, preferably by driving them to a dealer, but there is no one here in New Mexico -and the Colorado retailers tell me that they don't offer such service.

Folks in the southeast have Marc Koval at The Repair Shop (Georgia) and Bruce Sinclair at CMB Integrations (South Carolina). Does anyone know of options out west, much closer to me?

You might call Mark and send in the electronic panel. He fixed one for me taking the panel off himself and back to his shop. Then he shipped the panel back to me and I put it back on. Just a couple of connections to make which are apparent. If he let me try you should be fine.

I just finished refreshing the caps on my living room pair of DSP5000s 'smileys', and the improvement in sound is consistent with what I saw with my older pair of upgraded 24/96 5000s.

On this pair I went with 5W 680 and 330 Ohm replacement load resistors (I had previously replaced the resistors with 2W 680s when I first got them many years ago). Interestingly, the replacement 2W resistors I did at least 5 years ago still looked pretty good.

The caps looked to be original from the factory board and were all Jamicon. They looked fine by eye with no bulging caps or obvious heat damage. For the replacements, I went with Nichicon Ultra Fine Golds and Ansar Supersounds.

Having refreshed the amps on the DSP5000s and DSP6000s, it is also interesting to compare the two sonically. I like the bass response given the smaller size of the DSP5000s, but the DSP6000s with refreshed amps are really sublime with amazing bass and such a detailed midrange and upper end. It's really incredible what these speakers are capable of, especially given they were designed so many years ago. I have had Meridian speakers since 2004, and it's a pity I did not refresh the caps on the amps of any of my DSP speakers earlier.
