Crossover help?

Hi to all I'm hoping someone might be able to help.

I've tried to upgrade components within my crossover and now have no HF signal.

The tweeter checks out.

I've searched for bad joints , shorts etc but can find nothing obvious.

Today I've pulled the upgraded components from the Hf circuit but still have nothing.

Using a continuity test its all good up to the main cap and after back to the terminal.

I do get a bleep from both terminals so assume thats the parallel resistor.

I'm at a loss as to why its gone completely dead.

Anyone got ideas how to check the network front to back with only a basic multimeter?

Thanks in advance if someone has some ideas

Regards Ian

If you're getting continuity from binding post to speaker terminal has to be tweeter. if you applied too much heat for too long you may have fried something. Should always use heat sink, anti heat paste around fine gauge wiring.

The crossover was removed completely. The tweeter is still fine, checked. I don't have any form of heat sink, i have previously soldered much smaller components with success. The only items removed/replaced are resistors and a caps. The continuity is from HF +/- which is assume to be the parallel resistor? Regards Ian
