So much easier to fix electronics stuff when the boards were single layer.

Back in the 70's, when in HS, took electronics classes. The first was just basic stuff. The second you got to make stuff. The most popular was intermittent wiper controllers for cars. The third and most advanced class was TV repair. There was this new TV out by Curtis Mathis that didn't have any TUBES!. it was all circuit boards. However, it was designed to replace circuit boards like you would replace tubes in the older TVs. The surprising thing was the circuit boards didn't cost much more than tubes. Especially since the Curtis Mathis TVs were the most expensive. Back then you could get tubes at 7-11 convenience stores.

Used to have a tube tester and a oscilloscope. The main tube in the oscilloscope died and the there was no tubes to test so chunked em. About all I did with the oscilloscope was use it for a GIANT multi-meter. I still have an use my old Simpson analog multi-meter, it about the size of a lunch box. Haven't joined the digital multimeter age since all I ever check with it is to see if my car battery is charging or if I have continuity somewhere.
