Hi To use the current crop of FE-5680A's directly with the TBolt, you would have to tear it apart and get a wire into the C field circuit. If you didn't do that, you would have to stick a PC (or other controller) in between the TBolt and the Rb. As they come from the vendors, there is no voltage control capability in the units. There are so many flavors of this Rb that anything said about them only applies to some of them.

However, I can't find it now. I would not do it that way. My plan is to leave the t-bolt as is and then every 24 or so hours adjust the FE-5680A if required to better match the t-bolt. My hope is that after some time the FE-5680A will less and less frequent adjustments. This will be a while as my FE-5680A is still in the mail. I think the FE-5680A has to course of adjustment to be used in the "fast" control loop inside the t-bolt Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
