    Hello,

    After searching around, I cannot seem to find the Lexicon pro audio website.
    I found a Lexicon home theater product website at lexicon.com, but no links
    to the pro audio stuff. (???)

    I can't remember whether or not Lexicon still supports the PCM 42. If they
    don't, I seem to remember that at their website they had recommended a
    certain repair shop to handle older unsupported Lexicon products.

    I have a PCM 42 and PCM 41 that work, but sonically they are ailing. The
    delay output signal is low, a tiny bit distorted and poor tone. I compared
    my units to a friend's super mint original PCM 41 and his sounded way
    better. I guess my units need some service.... perhaps caps, or...?

    In anycase, I wish to have my units repaired by a reputable source. Any
    info regarding this subject would be greatly appreciated.

    Thanks - wg

    I have a print-out of all the PCM42 schematics, which were downloaded
    from the Lexicon site not too long ago (maybe a year or two). Dunno if
    they're still there. Jim Fabiano sells schematics and manuals for a
    lot of money. Yours has an analog problem. It could just need a
    recap, though it seems like the low-pass filters on the DACs in all the
    old Lexi gear has a tendency to crap out. I had a 200 reverb in here
    with the same problem, and I found that it is not possible to find
    replacements for these custom potted filter modules. So I built a very
    simple passive RC filter in its place. The owner of the reverb agreed
    that it was actually a substantial improvement in tone. Apparently a
    little aliasing on the output is better than a steep, harsh, phasey
    brick-wall filter. I suspect that's what designers of modern
    converters have determined as well. Feel free to e-mail me for more
    info.
