Does anyone know where I can rent (at a reasonable cost) or borrow an ESR meter in the Pittsburgh area? A suggestion in this thread said I might have a bunch of bad filter caps in my non working Tek scope. It would probably be just as easy to just replace them since they probably need to be replaced anyway but it would be nice to know if the caps are my problem. Where can I get one of these things aside from shelling out the $$$ to buy one. I know I can build one with another scope, a function generator or a 555 timer (and I guess even a PIC which I have on hand). But I do not have a another scope.
