I am not buying oscilloscopes anymore but my only portable (luggable) scope recently died, so I got something a lot smaller but still vintage: this cute Sony/Tektronix 335, from 1976 I believe.

"Rat's nest" or "Manhattan Style" prototyping (or however one would like to call this particular hybrid variant) is fun to do and has some sculptural charm. Tomorrow we'll see if this actually does what it should do.

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.

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.

Today, in the age of AI, I made this very modest adjustable power supply because I needed it and because it is nice to build one.

Evaporating pcb traces turned out to be a symptom of a failing rectifier and the latest update is that this may not be the end of it either.
