Has anyone ever worked on a National XCU 50 crystal calibrator? Specifically I am curious about the Valpey crystal in it. The one meg side is not working and I believe the quartz slab may be cleaned to restore operation. The caveat is I am a bit hesitant to open the case without knowing what to expect.
Has anyone here ever taken one apart that can tell me how they are constructed? 73 Jim/W5JO ______________________________________________________________ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/[email protected]/ List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Post: [email protected] To unsubscribe, send an email to [email protected] with the word unsubscribe in the message body.
