Just wait. I'm building at fast as I can (a few hours a week) These units are to new to expect much long term data yet. Now I think it is a good time to write about "ideas". Most people who bought these have not even figured why they need one yet. It will take months or longer before we know how good the "retrace" is on these, that's where you set it to E-12, power it off for a week then power it back on and measure after warm up. What is a statistically valid sample size and each retrace sample takes at lest a week. I suspect it will take longer than 7 weeks to have measurable aging. What is the physical cause of an Rb to "ageing" 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.
