Building an ESR Meter

Hello again!

I've found a very interesting circuit wich I would like to share. Its a capacitante / ESR meter, to test the capacitors without desoldering them from the PCB. Beautiful for speeding up repairs.

Attaching the schematic directly would be great, but I don't want a copyright incident.

The attached text describes an even better schematic (includes a SHORT indicator light), but the guy didn't attached a !"#$@ diagram I've uploaded the text hoping that someone with good memory may remember the magazine, and the precious schematic attached to it
