I know Stan, what bothers me is the SOURCING OF THE PARTS. But never mind.

That's really not difficult. Download Stan's instructions. www.beresford.me/downloads/CMIIGFU.pdf and. His instructions on opening the chassis to get at the PCB. Re read the thread which will point you to some of the caps needed from eBay for less than a fiver. If you want to fit the bypass caps as Martin has, PM me your address and I'll pop a couple of Oscons in the post to you. All the rest are readily bought from Farnell. Once you have all the components and if you don't feel confident yourself (some of the surface mount items are really small) find a local electronics engineer to do the job for you. Everything you need to do this job is contained within this thread. Whatever way you choose to do it, you really can't go wrong. |

You can source all the parts from eBay, put them all in your basket. One purchase!

I have finally managed to complete the start up pages for the support, mods, instructions, etc. for the Beresford products. The direct link is www.beresford.me/S/home.htmHowever, it is also accessible via the Technical menu option on www.homehifi.co.uk, which will redirect you to the technical site. If you notice any errors etc., please notify me so that I can correct it. The site has many of the important mods discussed on AoS, plus a few that were only known to a select few people. It is early days yet, but I hope to build it up over time with many of the important bits that were discussed and concluded on threads on AoS. The main reason for that is to save people from having to browse pages and pages of threads just to find something that was discussed many moons ago, and an answer and solution was then found. If there are any additional suggestions, just let me know and I shall do my best to sort it out. I have done my best to make the site friendly to the various type of screen platforms. So let me know if your device can't load the different pages correctly. Stan |

Really nice work, Stan. You might want to amend the typo "boddy" on page 2 of the TC-7534 mods.

Thanks for noticing that Martin. This thread itself is listed in the Caiman MKII mod thread link at the bottom of the page at www.beresford.me/S/faq.htm |

I'd like to know more about the 47000uF 5.5V Tokin supercaps. I've read the spec sheets, and can see the low ESR and obviously the high capacitance value, but I've not encountered these capacitors before. Why were they selected for this mod, and where else in hifi could they be utilised?
Anyone with experience of using them in other projects?
BTW I've done the mods on my Caiman and installed Stan's latest chip and it all sounds great!
Thanks.

They are very small for their capacity and therefore have a high energy density. I would guess that they are sensitive to over-voltage and I would never use them in an application where they can see too much voltage or even ripple. For applications like DACs, streamers or CD players they look ideal. Certainly the Caiman benefits from their use.

Why were they selected for this mod, and where else in hifi could they be utilised? I am lucky to have done a broad range of product development work across different fields. So I tend to pick up on parts designed for one section of the industry, that might be of benefit in another. That's how I picked up the 47000uF caps in a technical bulletin in a computer parts magazine, and decided to try it in the low voltage rail of a DAC. It's total overkill, but it is superior to any high-end part that you could possibly have used instead in that same location. It is a hard to get item. So I am using a Capacitance Multiplier instead in my next project. |

Thanks for the info Martin and Stan.
These caps seem to be fairly easy to get hold of - the usual suspects: Farnell, Mouser etc. and of course ebay. It's always nice to find out something new. I might try and see how they would suit any of the sources that Martin suggests i.e. streamer/CD/DVD player etc. Something to investigate....
Thanks again.

I have been working on a mod that takes advantage of the use of a 15V power supply to power the SEG. Anyone with a 15V power supply in the UK who's fingers are itching to dig out their soldering iron again this autumn/winter?

Sorry, not at the moment Stan as I am completely sold on 12V battery power for the SEG.
