Note that the +12 for the oscillator goes through a 1 ohm resistor to a linear SO-8 8L08A regulator to supply +8 to the oscillator inside the OXCO case. There is also some bypassing. I had posted some photos of the innards some time ago. -Arthur _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
