Valley Proofs

I completed today a purchase of one more piece of Silicon Valley history, the EIMAC 100TH   Transmitting Triode Radio Vacuum Tube. For $22 I will receive a working triode, with the birght prosepct of lighting its filaments again perhaps not to transmit but at least to show its colors on the oscilloscope. EIMAC operated in nearby San Bruno this was not an accident, as the San Francisco Bay Area was an early center of ham radio with about 10% of the operators in the United States in the early 30's.

The DMV actually did update the records, and their systems show the new expiration date. The officer said, to keep the expired paper extension nevertheless but as far as they are concerned - they have good data.
