[TenTec] OT: swapping a Tantalum for a Electrolytic

[N9TZL]

Not to be a killjoy but: Personally I would be careful in the wholesale replacement of electrolytics with Tantalum caps. Tantalum caps can not stand the inrush current that electrolytics can which can cause the Tantalum cap to fail. They require some series impedance from the voltage source to the cap so as not to exceed the inrush current.

I agree it can be done in some places just be careful.

Couple of references!

IMHO There is zero problem doing that. The Tantalum cap has a better ESR
rating and better performance at cold temperature.
