HP 5245L Nixie Counter - Part 7: HP 5264 Preset, HP 5262 Time Interval, HP 5257 Transfer Oscillator
We test a pile of new plugins, and fix the king of them all: the HP 5257A 18 GHz Transfer Oscillator. While we are at it, we demo the HP 5264A Preset Unit and the HP 5262A Time Interval Unit. This completes our repair-a-thon! No kidding, we repaired them all, the main counter and 10 plugins!
