Yes, that's a pity... They are easily available throughout Europe.
They have some really nice caps, like these 4.7uf with 5mm spacing. 😀 These appear to me as a quite perfect input coupling cap. At least you have 2 couples...
We could arrange a group buy for these ? (north america)

Hi Mike,
That's true. But I had to rely on you for that. Many thanks by the way! One pair is in use in my Marantz 300DC as an input coupling cap. 😉

Compared to the previous input caps, the wimas have easily 5 times the price.... These wimas cost an incredible 1.70€, compared to the 0.33€ of a bipolar 10uf. No wonder Marantz used the elyts. 🙄

Hi Mike,
There is that, and also what was available in the late 70's / early 80's. Those 5mm caps are wonderful things!
BTW, changing to the film caps does improve the sound quality. I have found that bypassing the feedback cap with film is a big help. No cap would be better of course!

Yes, bypassing the elyt feedback cap can remove much of the colorization.
I guess, in the late 70's, these film caps did not exist yet.
I was myself amazed when i saw these wima caps.
About skipping this cap, having jfets in symasym as input devices it's possible to skip the feedback cap, but it will still increase dc-offset factor 45. It should stay below <100mv... Needs experimenting.
Have you already tried the lineartech devices ?

Hi Mike,
I won't try anything until I get my bench sorted. I need to establish a baseline for comparison.
I will say that the Symasym exceeded my expectations. I highly recommend it in it's present form. Pavel and yourself have done a great job. Many thanks for releasing this to fellow DIYer's!!

That's really overkill ! Yes, go for polyester/styroflex, not ceramic for C14.
Mike
If I could find polystyrene or polypropylene caps at 22 pF
I would gladly use them.
If I couldnt find plastfilm caps I probably would go for ceramics.
NP0 are, what I know, the best quality ceramic capacitors.

Even if I searched for a while, I could not find any datasheet for these mica.
I could not even find out the homepage of the manufacturer SECME.

I can't find the 4.7uF in England (Farnell stock smaller values). Do you know a German distributor that accepts crdit cards or paypal, and will ship to UK?
