Electrolyt as DC blocking
 
Hi anybody know how many dc volt elektrolyts can block ?

use bipolar - with full rated V for both directions - higher V in excess of needs reduces measureable distortion

Or make a bipolar of two electrolytics. Connect "-"'s one to the other. Take into account capacity is halved and each cap must be rated max DC you block.
PS. However, sonically not the best idea.

My I/V stage has + 10 V out. I know it is + so normal electrolyt must be ok if I use + as in ? However they let around 4 v pass though.

Impedance after them is 47 kohm.

Just discovered bipolar blocks. There is 2 on each output. There is + on one and - on the other so the one on - has to be reversed.

You don't want elcaps on i/v out. Use good film caps MKS/MKC or MKP. From wima or roederstein/vishay

I do not like filmcaps. I think electrolyts is better when there is no place for DCA cast. Have you ever tried electrolyts where there is a few volts on them ? Eletrolyts off best quality offcourse.

Yes, I have tried and compared film to electrolitycs. Replaced elcaps or bipolars with styroflex or polycarbon in a couple of CDs, amps (SS & VT). The difference is huge across the whole spectrum of music.

Nice, but Why is there no "curves" for electrolytics?
