Default Elna Silmic II capacitors

On Friday evening one channel suddenly dropped in volume and lost it's top end. This was followed by a nasty burning smell from one of the 300B PSE monoblocks. I turned everything off and went to bed!

When I tried the amp again on Saturday I noticed one of the 300B valves was getting really hot. A bit of poking around with a test meter and a shorted cap was soon identified. It was a 100v 100uF Black Gate cathode bypass cap.

Black Gates aren't available any more, so I've ordered a quartet of the Elna Silmic IIs to replace all the Black Gates.

Has anyone used these? Do you have any views on them? Do they need to burn in like the Black Gates, which always needed a fair bit of running in before they "popped" and start sounding right.

Thanks.

Guy

Default Re: Elna Silmic II capacitors

Hi Guy....

I used these long term in my homebrew phono. They are better than most lytics I know of with the Exceptionof the Black gate and a few of the other Elna caps. They make a Silmic specially for audio and it is called the Duorex
series.

Also worthy of a listen is Panasonic fine gold and also Elna stargets.

If the blackgate was a small one you could try to get the right values using a few different caps and bypassing etc.....
