    EV 12TRXB vs SP-12 + T35. I have questions.

    Greetings, My living room system is a pair of EV Aristocrats, one with a 12TRXB, the other with an SP-12 + T35 tweeter/horn. I believe that the 12TRXB is basically the same as the SP-12+T35, just as a single driver. They are being driven by an upgraded Elekit TU-8100R, ~8 watt SET amp. I...

    Will a Wharfedale Super 12 fit in an EV Aristocrat cabinet?

    I have a third Aristocrat cabinet that currently has a SP12B driver. Will a Wharfedale Super 12 fit without modification? I find the SP12B to be a bit dull.

    Does anyone use a rechargeable portable CD player?

    Greetings, I landed a great new job this summer. Unfortunately, now that school is in session, my commute is usually an hour and forty five minutes each way. I don't listen to commercial radio, and the independent stations aren't cutting it. I have a library of over 800 cds to listen to, so...

    Does anyone recognize this mono amp? Victor SSA-110

    Greetings, I picked this amp up from an auction in CA about 3 years ago. I posted about it then, but I thought I would try again to see if any of you fine folk have ever seen another. I can't find anything on the internet. My assumption is that it is an extension mono amp to turn a system...

    Why would a battery charger mess up FM reception?

    Greetings, My garage system is a Sansui 880 with original CSW Ensemble satellite system. The receiver is plugged into the same circuit as two Milwaukee chargers, one an M12, one a combo M12/M18. If there is a battery plugged into the M12/M18 charger, the FM reception goes all to hell. If...

    Has anyone opened a Grado SR325 can?

    Greetings, I have a broken connection in the left earpiece of my Grados. I assume they are glued and a hair dryer should work to loosen the glue. Any advice? Just heat and (carefully) pry apart? If so, what kind of glue to reassemble? Thanks!
