Continuing from daily bread. Berhinger super-x pro crossover...

Got three taps off the toroidal, all seem to be 73.x vac to ground. mv between each??? So far rectifier diodes check ok, main filter caps check ok, not familiar with how to check these voltage regulators, 7851a and 7951pi.

That would be LM7815a and LM7915a Andrew. Links below.

Thank guys. Life interferes once again. I’ll get back to it but at least my moms cat didn’t starve.
