Question about Audio Players & Recorders

1 Answer

We have a peavey fire bass 700 and we were using it in an outside program. We plugged up a sunn bass cabinet with 2 15' wolfers then we plugged up an additional cabinet with 2 12" wolfers. Both cabinets were 4 ohm. The amp went out and we aren't getting any lights on the face of cabinet. We took it apart and tested the wires to see if we were getting power and there is power going into the copper coil but not coming out. We thought that it might have blown a fuse but the 2 fuses that we can see look ok. What do you think is wrong

This amp is designed for a 4 ohm load. By connecting the two cabinets, you presented a 2 ohm load to the amp and overworked it. I suspect that the amp will now need repair. I don't know the particulars of your model, but if you have a way to check transistors, you may be able to repair this yourself. Let me know if you want to attempt this.

I want to know where to buy a Peavy bass cabinet serial number 3E-01473871


Perhaps you needto ask about a model number rather than a serial number. It's doubtful you will be able to find the one specific cabinet with this serial number. Your only hope would be to contact Peavey directly to see if the owner registered the warranty.

Trying to connect peavey tour 700 to a trace elliot 1518 bass enclosure. Plug the enclosure to the back of the amp. Then plugged my bass into the high gain. Turned it on and nothing happens.


Check continuity on all cables, try a different cabinet with the head and a different head with the cabinet and the bass with a different rig to see which part of the chain isn't working, make sure the volume controls are turned up on both the amp and bass. Once the problem is narrowed down it will be easier to advise you.

I use an SVT450H with the SVT410E and the SVT15E both 8 ohm Ampeg cabs. I have to have the main gain on 5 to 6 and the master volume on 7 to 8 and that is in smaller venues. I use a 1964 Fender Jazz Bass...


Check to see the phasing of the two cabinets and the cable. Take a 9 volt battery and touch it to the end of a cable that is plugged into the cabinet. The + of the battery has to be on the tip, and the - to the sleeve. See If the speakers move outward. Check each cabinet if they do then they ae in phase. Now try it with the second cable the results should be the same. If not and they move in the opposite direction then that cable is wired wrong. If one of the cabinets move in the opposite direction than the cabinet is wired wrong. You can also run one cabinet at a time if they sound louder by them selves that should also tell you that something is out of phase.

Can you directly hook a sr16 to a peavey bass speaker cabinet using the output mono on the sr16 to send or retrn on the cabinet?


You can, however a bass speaker cabinet will NOT handle the higher pitch sounds needed for cymbals and snares, etc. You would connect it to the return AND doing so would DISABLE the other inputs of the bass speaker cabinet.

If you want both a guitar and drum machine into the cabinet, you need at least a small mixer or a speaker cabinet that can take two channels input simultaneously.

Plugging into the "return" of the cabinet DISCONNECTS the power amp from the preamp section in the cabinet.

Bass tone problem


Both of your problem amps were made in the '70's or earlier. It is entirely possible that the coupling capacitors are failing. This is an issue for a service center whether it is caps or something else, like failing tubes.

The good news is that installing metalized polypropelene capacitors will make those classic amps sound incredible.

Bass amp settings


For rock and slapping you are going to want to set the Bass and Treble controls high and the Mids low. For music such as Jazz you are going to want more mids so that your sound will be fatter. If there is a button marked "Mid-Scoop" you'll want that on when slapping.
