Is it still alive?

Post by izzy wizzy » Wed Dec 26, 2018 1:00 pm

I'm not sure whether this guy is still alive. If he might be, how could I tell? He's a BG non polar 470u 16V so unobtanium. I want to try him as a cathode bypass in my phono but don't want to let blue smoke out of him or anything else for that matter.

You could measure the value and the leakage current but that is a big dent. I wouldn't trust it, even if it measured OK.

You can make a non-polarised cap of that value with two 16v 1000uF polarised electrolytics connected in series, +ve to +ve... (or -ve to -ve)

Easy.

BG = Black Gate?

I have a box full of the critters somewhere, you're welcome to whatever is useful.

Thanks Ed. It wasn't so much making another. I have 4, 1 squashed. I wanted to parallel then to make 2 x 1000u and try it as a cathode bypass on the first stage of my phono to try something out.

Yes it's a Black Gate. I wanted to use that type as I know they're good. If I pursue the above, then maybe I'll have to consider something else. Thanks for the offer. What 1000u or 470u types have you got lying around?

Cheers,
Stephen

Hi Stephen,

I have Elna Silmic II in that position, sound nice to me but not tried BG so can't compare.

I'll sort out what I have and send pics and values. (When I have my other problem fixed, lol). I also have some spare Elna Silmics.

Just IMO - I messed with BG a while back - didn't do much for me and got thoroughly fed up with the "burn in time" until when they're supposed to start sounding good. Have and still use Panasonic FC series radials (recommended by Nick G), seem to do the biz for me. Image
 
I never make the same mistake twice. Instead I prefer to fill my day with a variety of different mistakes

All good suggestions for substitutes welcome as well. Thanks for the suggestions. I'm not wedded to anything in particular as I'm not really a component comparison person. As long as a bunch of people like them, I don't have to sell the children (tho tempting) that usually does it for me.

Cheers,
Stephen

At the time I was working in any detail on the phono amp, I found the red 'NH' black gates to be better than a lot of other stuff I tried. Definitely better than Elna Cerafines, for instance.
The more cost-effective one I would like to compare in detail now is Nichinon ES 'Muse' caps ( non -polar ) used as a pair ( nose to tail , paralleled ) which seemed to do a very good job as the input caps on a chip amp.
