Is there a fuse in a peavey sp2 for horns

This is based on MOST cabinets like this: First look for any small screws which are usually through the grille near the top and bottom that retain the grille. When those are removed, one has to pry the grille out of the grooves at the side by dishing the grill outward at the center so edges come inward. There often is a "U" shaped rubber strip along the edges that will need to be put back on before grille is dished and put back.

Note that SOME speakers have a fuse or a polyfuse to protect them from excessive current. If yours do not, consider puttin in polyfuses to protect them. They are available from Digikey.com.

Calculate the hold current based on the pwer rating and impedance. Take the square root of the rated power of the HF divided by the impedance and choose aa polyfuse that will hold that current and one that will standoff the peak voltage of your amps. Calculate that voltage as the square root of the max power of your amp divided by the LOWEST impedance allowed for the amp.

Set the filter to search for "Radial" type package and find suitable rating in the list that comes up.

The lamp is an "1156" lamp... replace with that part number. Here :

Or you can find it at auto parts store.

LIKELY the polyfuse device is ALSO gone... Probably similar to this one (1.1 amp, trip 2.2 amp):

or this one (1.85 amp, trip 3.7 amp):

Check the resistance across the woofer connection points. Using an ohmmeter, you should se around 6 to 8 ohms. If there is no continuity, you have a blown speaker.

Actually its pretty funny thing with those speakers is the "fuse" is Actually called a Lamp in this case. These are what they call a " Red Dot Fuse ". in all the years i've been doing this i've never thought to look up the value haha. Just have to know there are Red Dot lamps and Blue dots and No Dot. If you examine the LAMP you should see somewhere close to the ends ON THE GLASS a color dot of some kind. almost like someone painted it on there. Red Dot Lamp. any parts distributer for people like Harbinger, Peavey, and B52 will KNOW what your talking about
