[EMAIL PROTECTED] made an utterance to the drakelist gang ---------------------------------------------------------------------- Bob Thanks for the reply. This explains why the what I thought might be an overtone frequency is not a multiple. I'll contact international when they open and arrange to have the crystals replaced.
