Brown phenolic paper? But even if not, them all used one-sided PCBs, be it fiberglass or phenolic, and those have no through barrels, so the solder joint is only held by glue and not by a through barrel; that makes the joint separate after a couple of touches due to the glue burning. Or due to the weight of parts.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
