Learned about slew rates and other limitations of signal amplifiers, but got to 70V p-p maximum output swing with a -3 dB point around 1.5 MHz.

For the new crystal experiments I need irregular agglomerates more than I need the canonic shapes.

Preparing new crystal experiments and the most suitable transistors I have turn out to be these new-old-stock in their similarly new-old-bag. These were designed for driving core memory arrays.

This week I was experimenting with a principle that was explained for the first time *exactly* a century ago, to the day.

A very interesting rabbit hole that opened up when I wondered when and how the piezo-electricity of ammonium dihydrogen phosphate was discovered.
