Default The first tube "integrated circuit" (1926)

you'll find this PDF from Radio News, 1926 to be quite interesting:

I've got a few of those vintage Radio News magazines and have seen that article in one of them. Note how the passive components like resistors are sealed in their own glass cylinders within the valve envelope to keep their outgassing in check. There is a lot of neat stuff in those old magazines. Imagine that they were able to fill an electronics magazine cover to cover before there were computers! I stoped subscribing to Popular Electronics when it became a computer mag.

Once again, everything old is new again. Those 1926 items look like the very 1st integrated circuits ever made to me.

They contained metal film resistors when everyone else was using carbon composition. That took a while to catch on too.
