    Apropos of the above (and FWIW): I've always kind of wondered why the "back side" of the cone suspension attained the moniker spider?

    Now, I'll grant you that early "spiders" were, perhaps, more arachnoid in morphology -- such as the spiders on my venerable (and seldom unboxed) Altec 604B Duplexes (and on my single, rather scroungy, 603B "Dia-Cone").

    Yah, it's true! :)
    It counts minutes and seconds... "digital clocks" like this (and even cruder ones) are quite familiar to those of us who are... umm... of a certain age. Or an uncertain age, once we can't quite remember any more...

    That Wollensak/Sanyo 8-track deck's "digital" timer is bit on the "crude" side, but the little geared wheels on it are indeed calibrated with minutes and seconds. If (!?) it is driven by an AC synchronous motor, and the gears are pretty precisely cut, it should be good enough to ensure the track change ka-chunk doesn't fall right in the middle of an In-a-gadda-.... :#

    OK -- I am in full-on reminisence mode after posting that image. That's the "digital" filmstrip clock used by Zenith in one of their "Circle of Sound" clock radios in the very early 1970s. I was the proud recipient of one (birthday present) ca. 1971 (i.e., almost exactly 50 years ago). It woke me up (to WBAL-AM 1090)
    for school for years, and I also used to listen to the Baltimore pop and rock (AM and FM) radio stations of the early 1970s on it before I set up a "hifi" ca. 1974 or 5 from components gleaned from my father. :)

    It actually sounded pretty good (for a plastic cabinet clock radio)! Zenith sold all kinds of cute loudspeaker configurations (large & small, cheap & expensive) over the years -- this particular "Circle of Sound" model has a downward firing "fullrange" (ahem) driver with a diffuser that serves as the radio's base. B)

    Borrowed internet photo -- but I still have mine down in the basement. It is on its second clock, and I don't think the second one works any more, either... but it was a good ol' radio, and (probably) still is.

    EDIT: Oh, I forgot to mention -- the above-mentioned radio was acquired from Luskin's in Glen Burnie, MD. "Where Jack you know will save you dough!"

    ahh, memories...

    ;)

    I remember that ad :)

    Probably still better than the cactus needles of the Victrola era, I suppose. :#

    I don't think they're good for too many plays before replacement's required. :|

    I seen an old victrola or something like it that used wooden needles. Strangest thing I ever seen.

    Do you use this one on an S arm? :)

    Well...cactus cantilevers are being used today. Here's a close-up pic borrowed from VinylEngine, member Delta667.

    Dmitry does amazing work. I think someone in South America sends him cactus needle stock. Peter Ledermann (at Soundsmith) and others have done this as well.

    Isolation transformers (with several output voltage taps) are actually handy... so handy that... umm... I did already have one. ;)

    I picked that one up because of that RCA meatball logo, age, and... well... 'cause it's RCA. I know this guy who's... a bit of an RCA fan. I thought he might enjoy adding it to his collection of... interesting RCA things*.

    Oh, and the price was right, too, you know? B)

    * Interesting RCA things like a pair of these, you know?
    (OK, the "super" tweeters aren't RCA... but the rest is)

    Every so often I come across a photo online that makes me think: "At least my setup isn't THAT bad"

    so -- I have developed a taste for a blog called "Curbside Classics" in recent months.
    I've seen some weird stuff there -- some of it very cool (e.g., a 1930s Chrysler Airflow... truck design).

    In my email inbox today, though, was a heapin' helpin' of automotive cognitive dissonance.

    I think I was vaguely aware of this... umm... project. I'm not sure I needed a reminder. ;)

    I dunno -- a Reliant with six wheels might've been a force to be reckoned with. B)


    I was struck by how much like some of the Chrysler/Mitsubishi products of that era the B&S hybrid resembles -- remember the ol' Dodge Omni and its ilk? :)

    Brooks Stevens Associates did the (ahem) coachwork for the B&S six-wheeler, according to the post. :#
