  • Damaged Resistor In EV Crossover

    I have been searching for a replacement of a damaged resistor for an EV crossover.

    The two resistors on the left seem to be bent out of shape. Hopefully, they can be nudged back upright without further damage. But as you can see, the resistor on the right (10 ohm, 20 watt) appears to be beyond repair. I was thinking that I save the legs, cut our the resistor piece, then solder in a regular ole Ceramic resistor across the existing legs.

    Any other ideas?

    That will work. But have you looked for a resistor with legs like that? They may be available.

      Thanks Greg....

      I am hoping I can straighten the legs on two of the three resistors and that they are ok. For the third, I will cut out the "resistor" piece and try to solder the replacement onto the existing legs. I'll make it work.

      I picked up some old Electro-Voice S-122 (12" woofer) cabs that did not have the crossover units. The big brother to this cab (the S-152, 15" version) uses the same components and circuitry for the crossover even though the Xover says "152" instead of "122." The nice thing with using the original Xover is that it fits into the existing cutout without mods to the cabinet!!

        Straighten at your own risk.
        I gave up trying to straighten bent pot shafts that were still usable as they often broke. The legs on those resistors only need to offer rigid support and keep the heat off the board.
        I only say this because I think that the metal on these type of legs is a bit more brittle than the normally bendy type leads we are used to.

          That^^^

          WHy bend them again? Leave them leaning like that, the resistors don't care, and every time you flex the metal legs, you are that much closeer to metal-fatigue snapping it off.

            Even better, search Mouser catalog for same resistors with same strong legs, order all 6 of them (3 per cabinet) and sleep like a baby

            Cheap insurance.

              Those look like R.G. Allen / Micron Power Resistors with the legs. I see some in this Micron Power Resistor sheet at R.G. Allen:

                Do they sell in small amounts?

                  DigiKey has them
                  It's the SQZ series of snap in resistors.

                    Thank you Gents.... I will take a look at Digikey and R.G Allen.

                    Much appreciated....

                      A lot of the older tv's used these type of resistors......I believe I still have some but not in the value for a crossover....I use one for a cap discharge tool.....220 ohm at 30 Watts...it is a big sucker.....
