Lexicon website? - PCM 42 repair?
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 |

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. (???) That's now at http://www.lexiconpro.com 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.

In anycase, I wish to have my units repaired by a reputable source. Any info regarding this subject would be greatly appreciated. Bob Sellon (former Lexicon employee, original designer of the JamMan) used to be an incredible resource for this sort of thing. (He also designed an amazing memory expansion upgrade for the 42 that David Torn & Bill Frisell still use.) Sellon's still got some info at http://www.stecrecords.com/gear/pcm42/index.htm, but I've heard he's gotten out of the hands-on repair & upgrade end of things. Also might want to try http://www.jimfabiano.com/ Sellon recommends him, though I've never had any direct experience with him. |

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