I seen similar decade modules in some russian counters dated early 50's... But much more funny thing was old dekatron-based pulse/time period counters. They was widely used in a nuclear research in late 40 - early 50's, I still seen one of them working in some lab in late 90's (12 decades in a row if memory serves me correctly). Guys there keep one unit and some stock of spare dekatron tubes from decomissioned ones as a sample of old technology. ;) Other funny thing I seen there - old tube secondary frequency standard (CH1-27 if memory serves me correctly). Two large boxes, one is precision ovenized xtal oscillator with standard frequency broadcast receiver, scope to tune its own xtal by Lissajou figures and some other goodies, other box is frequency synthesizer up to 600 MHz. Don't know how much it weighs, but certainly over 100 kg total. -- Best regards, Yuri mailto:[email protected] _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
