I got Thur the resistance check ,when I  put power to the eros I blew the 10uf tantalum. I ordered more but I am fear that this was a bad thing to do. What could this involve? And what could have gone down with tantalums?

double check that  you have the polarity correct,  tantalum's do not respond well to reveres voltage...John

The tantalums are there to prevent instability and oscillation in the regulator chip. It's unlikely that you have damaged anything else, and if you did it should be easy to figure out what and replace it - there's nothing expensive in that circuit.

Thanks Jon,and Paul. I really hoped I would escape without this kind of bone headed mistake. Eileen sent me out some today,so it sounds like it this is not the end of the world. Jann O.

Jaan - just a suggestion... Next time, embellish a bit more... you know, how it singed off your eye brows. Made you see god... That generates a lot more interest from the peanut gallery... Just a thought.

I don't know, every time I embellish...OK, Lie.

All it gets me, is scorn and harassment ;)...John

Paul, Can I go ahead with voltage checks w/o the tantalum caps in place?
