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.
