    The LE-8-101 is no doubt stamped on the cone. Most if not all of the 33's had unpainted
    unmarked LE8's installed.
    The LE8T came later. Basically the same driver.

    2440 mount

    if this is the clamp your referring to you can simply make one or have a machine shop do it...bolting that beast (2440) in is definitely a two man job. :banghead: good luck!

    Sweet!

    I remember reading an article on a blindfold A/B comparison between a high-end Threshold and a B&K. The reviewer actually preferred the cheaper B&K...comparing it to a tube amp.

  25. serial number

    Hello, I'd be curious as to how you determined it's build date. Mine, (278) dates to '59 also.
