Fender BXR100 Questions - technical??

Discussion in 'Amps and Cabs [BG]' started by Swimmer, Jul 20, 2009.

  1. Hi,

    I have an old, broken Fender BXR100 15" combo amp and am womdering if is worth arranging to use the speaker and cabinet as an extension speaker for a new combo I have.

    The amp part is toast because the knobs sheared off in transit - cheap plastic.

    There are several specific questions that I'd like help/comments with/about.

    1) I understand that the 15" speaker is a "Fender Special Design" with the following numbers on it 15", 040580, 151035, 67-97240699, 4 OHM, 62
    These notes are in various places written on the side of the magnet. Is this speaker worth keeping and using? Does anyone know what kind of speaker this is and what capabilities this speaker might have?

    2) How in the he** do I get the amp out of the cabinet? I want to rid of it and use the speaker and cabinet only.

    Thanks in advance,

    Its a 4Ohm speaker, so unless your head is good down to 2Ohms, no dice.

    I did this very thing to a BXR200 combo I owned. The head crapped out on me so I removed it, installed a jack panel on the rear and used it as a cab. Fender did use specially designed 4ohm speakers but if that's an issue, get an 8ohm replacement and keep it moving! As for removing the amp, there are screws on the top and sides (IIRC). Remove them and the amp should slide right out.

    If it's just a matter of having broken off knobs, that doesn't mean the amp is toast, only that it has broken off knobs.
  6. Rickenboogie,

    Well the volume knob sheared off and the back of it is integrated into the PC card inside, it would be a big (for me) job to take apart the card and it's wiring, unsolder or otherwise dismantle the potentiometer and replace it without killing the thing totally. Also, I don't really plan on using it any more as an amp. Also the speaker was hard wired (into a special plug) onto the circuit board and had to be cut to be connected to anything else.

    I'll bet I could buy a whole working one on Ebay for $100 or so.

    Anyway, I took it all apart, hooked up a jack to the cut speaker wire and plugged it (4-ohm 15") into the combo as an extra speaker as well as an 8-ohm 3-way PA Speaker. Holy Earthquake Batman! - The pots and pans upstairs fell off the counter upstairs...lol.

    See my other threads for what happened next, lol.
