SSL 4K/6K/8K next level recapping: Film Caps! WIMA MKS 10uF GROUP BUY OFFER

(1/2) > >>

marcmozart:
On my journey recapping my 1992 G-Series I discovered WIMA MKS2 Film Capacitors as a replacement for Electrolytic Capacitors.



The advantages compared to Electrolytics are tremendous:
- No ageing - never recap EVER: Operating life 300.000 h (= 34 years operating at 100 degrees C)
- Capacitance does not drop with frequency (it does up to 10% in Electrolytics between 100Hz and 10kHz)
- 10% tolerance
- Very low series resistance
- As a result, much less degradation of the signal

So far, I have used them to replace 0,47uF and 1,5uF Caps, very few of which are used in our consoles. (G-Series Logic Card, Power Supply Regulators)

To really make a difference across the console, large quantities of 10uF 50V Film Caps are needed, which is the largest value available with 5mm Lead Spacing.

Note that prices are still over 2 € a cap (ordering 100) and we need about 200 of those on the Centre Section, and more than 800 for the channels on a 48-Channel Console.

The lowest offer I found is at Conrad in Germany - they sell them for € 0,83 each if you order 1000.

GROUP BUY OFFER !!!
I am personally planning to recap my centre section with those, so I need about 200. If we find 5 people doing the same, I’m happy to order 1000. Let me know - it takes 15 weeks for them to ship the order though.
Just keep in mind that you only do this once and - for about € 170 you NEVER EVER have to recap HALF of your consoles centre section again.

Artur D'Assumpção:
Sad they are so expensive! If it weren't they price it would be an awesome replacement!!

Do you think that might have any impact on the sound? Or any negative impacts?

Cheers,

Artur

marcmozart:
These Wima's are much preferable to Electrolytic Caps.

If anybody wants to give this a go, let me know. Just need 2 people to join in, and I'll order them.

Hey Marc,

Hi Martin,
I just discussed this with my assistant yesterday. Let me find current prices. And, of course, it would be helpful to find another person to join... anybody?
