Did arcade games REALLY use Tube-driven monitors??

[centralradio]

I was alittle confused with the topic heading at first .I had in mind of a all tube TV sets used as a arcade monitor.Some of us at home back in the 1970's probably playing the original Pong on mom and dads old all tube TV from the 1960's or an 1970's hybrid set as mom and dad watch their new TV .I have several RGB CRT monitors here from arcade games.With some electronics magic with a composite video input along with the H.V ,sync, color demode circuitry and audio amp .You can make a regular TV monitor out of it.
