Cab keeps going out

    I have an old Peavey Model 215 (from the 80s I think). I've tried a few different heads with it and the cab kept going out. I thought it was the heads until I bought a brand new Peavey MiniMax head. So now I'm realizing the cab is going out when I turn on my Boss Bass Overdrive pedal. It'll play for a few minutes and then it cuts out completely.
    Is the pedal just pushing it too hard?

    Bad connection seems likely. Plays for a bit, heats up a tad and opens the circuit. Can you reflow the solder?

    Be loose connection somewhere most likely.

    Black widows have foam in the voicecoil vents. Overtime it will degrade and break apart. And gum up the voicecoil.

    Never heard of speakers going completely dead from it. But people think driver is damaged or blown. And instead the voicecoil needs to be cleaned.

    I'll assume somewhere on the internet shows how clean them.

    I'd check both. Completely dead signal more likely a bad/ loose connection on the jacks or speaker.

    Sometimes even random stray objects go into ports. If metal they get attracted right to those big magnets. Could be shorting connections. Unlikely. But I've found weird krap in my cabs. From car keys to screws n bolts lol stuck to the magnet.

    Usually a speaker killed from to much overdrive is dead. It don't come back. But yes since it's hard to use good judgement when hitting speaker distortion. Cause with distortion pedal your already hitting distortion. I just learned over time and knew the feeling or certain spongy Ness my cab had when being pushed with a distortion pedal running. And what was what as far as overall distortion

    I have had a few speakers with intermittent voice coils. If you hit them with high power, they come to life and work for awhile; then go dead again.

    Does your cabinet have a biamp jack set-up feature?

    Interesting. Of all the cabinets I've tortured never had that.

    Man , that drive me nuts.
    I'd probably punish the speaker for failing lol. And freaking kill it on purpose.

    I do remember having a sub with actual bad connections. From the speaker leads/ clips on the basket. And the actual wires from the clips to voicecoil were bad/ intermittent

    This is the version that DOESN'T have the Black Widows. I was wondering if it was a loose jack as well. It'll literally play for a full 30-45 minute set until that last song (when I turn the overdrive on).
    It just has one jack on the back. I'll post a picture

    Do not play that last song!

    Does Boss Overdrive silence other cabs?

    If the cab cuts out completely, I doubt it’s the speakers.

    Not the biampable version.

    Likely an intermittent jack, wiring or even possibly the driver itself. Troubleshooting will identify the actual cause.

    If it only goes out when you use a specific pedal,
    maybe it is the pedal.
  12. Or the wiring to the pedal.

    If it is a 2x15" cabinet, and both drivers stop at the same time, then it is NOT an issue with one or both drivers (assuming a parallel connection). Check the input jack and any other components/cabling between the jack and the drivers. If all is good, then start working backwards by isolating and testing individual items (eg. instrument cables, speaker cables, pedals, etc.).

    Another thing I forgot to mention. I've used 2 combo amps (one a 250watt and one a 350watt) and used the Peavey as an external speaker and it never went out.
    Here's a picture of the inside wiring

    It looks like there are push-on terminals on the jack. Are either of them loose in any way? There are probably similar terminals on the driver, same question. Also, does it look like possibly the terminal from the yellow wire is touching the steel cup? That would cause a short.

    If the speaker works with other amps, it suggests the speaker is not the problem.

    What he said.^^^

    Try a different overdrive pedal.

    Hi Carmen :)

    You don 't want your cab to go out?

    Drugs are not a good solution! :D

    Cutting the pocket money? No TV after homework?....

    My Mom tried a lot of things! But that didn 't help either! :laugh:

    Without kidding! Your cab doesn 't like your overdrive pedal but it works without?

    Maybe the problem is not the cab! Try another pedal!
