I've tried peaking a couple of different LPRO-101s for maximum lamp voltage, and in both cases I found that while it was possible to achieve more lamp voltage, the short-term stability ended up being a bit worse. I need to do some more experiments when I have more time, but my preliminary observation is that peaking the trimmer for maximum output is not necessarily the best strategy. Hard to say for sure with n=2, though. -- john, KE5FX _______________________________________________ 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.
