Old Vacuum Tubes (or radio valves) used in the 1930's up to the 60's. The large tube is an 807 famed as a low power transmitting tube, the smaller one is a 60's vintage vacuum tube used in most radios and early TV sets and audio devices. The very small 'transistor' is one of the earliest solid-state devices that replaced vacuum tubes.
Together they represent a transition from the 1920/30's through to the 1960/70's.
The grey cylindrical objects are 'electrolytic capacitors', these can still be found in modern electronic devices where large capacity is needed. ... most commonly in those massive amplifiers that 'audio freaks' use in their cars to deafen everybody and produce that 'head-banging' noise... 'KABOOOOM KABOOOOM etc' that one can hear well before sighting the offending vehicle!
