HI I just came back from another 5071a seller. #1-#3 fatal error: max emult. #4 fatal error: overcureent (about 80uA) I put the tube from #1 to #4. #4 became a "max emult" one.
I think the tube #1 is really dead and the circuit of #4 is functional. Since the ion pump current was dropping slowly.(80uA to 76uA in 1 hour), is it possible to be back to normal? regards LiAng BI7LNQ _______________________________________________ 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.
