The only information I have left is a bottom portion of the serial number, which seems to be either "13125" or "13725" with a "B' afterward, and a service code of "H3.9-12." Can I tell from this information whether these are 50s or 50i's? (My recollection is that they are probably the former, but it's been too long to be certain.) -- DMR NYC ------------------------------------------------------------------------ DMR NYC's Profile: http://forums.slimdevices.com/member.php?userid=8790 View this thread: http://forums.slimdevices.com/showthread.php?t=42522 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
