Non Polar Black Gates break in? where to use?

60.225.57.238

Posted by spinnsound on January 17, 2007 at 05:50:31

I have opened up my favourite portable sony tape recorder to find there are 3 tantalum capacitors per channel in the signal path on the way to the recording head. There is enough space (just) to replace these with other more classy elecrolytics.
The tantalums are directly in the signal path but do have a small voltage of around 5 volts accross them. Would it be fine to use Non polar black gates in these positions, and if so do the non polars suffer from warm up time as much as the non polars. I have heard that the black gates afer being shut down for a while take a long time to re energise to work to their full capacity again. This would be a problem as the tape deck will not be used exceedingly often and then will only be powered up for short periods.
And does anyone have a comment for the pk miniature series black gates which would be a nicer fit into the little space in my walkman.
Thanks!
