Well I'm not a crystal expert, but have been burned enough times to make me crystal wary. I believe that the series resonance mode crystal will oscillate at a slightly lower frequency when placed in a parallel circuit. The difference should be slight, perhaps on the order of 0.1% (this is an 'educated' guess). -mike -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Mike Fahrion mfahrion@bb-elec.com http://www.bb-elec.com/ B&B Electronics Mfg Co ph.(815) 433-5100 ext.215 fax (815) 434-7094 707 Dayton Road PO Box 1040 Ottawa IL 61350 -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
