Use of Tantalum Caps in non-polar applications
« on: September 21, 2022, 02:57:27 PM »
Hello:

Can't remember where I heard it, but can tantalum caps be used in non-polar and/or polar roles?  As an example specifically, in the case of a PT2399 delay or chorus, can a tantalum be used for the 100n caps b/n pins 9 & 10, 11&12, or elsewhere where polarity was unspecified?  Where polarity is specified, self-explanatory.  I am getting signal passthrough, but there is a distortion effect which I think is something else entirely, but thought I'd ask the caps question.

Thx.

Hi Fatknuckle. Tants are polarized. Grab an audio probe and see if you can narrow down the distortion. It may require flipping the tent around, but probe it before ou go disassembling stuff.
