on someone finally looking for insulation AND heat transfer (D'Oh..)

I bought an Aussie designed clever (and small) ESR measuring device for that service (of course when the thing is split.. well, that's lucky). 2 LEDs read out the ESR; a clever IC-design, I thought. As you know, an ohms check will tell shorted, but a bridge won't know about the series ohms.

Anyway, have a few (!) 485s and I don't want to have to unsolder / substitute all those barely accessible thingies. The meter sits there waiting for me to attack the pile :( Wanna fix some switching supplies accompanied by rest of 485?

As to 454 BW being adequate.. I thought you wanted to find Truth, not just an approximation!
