EM Solved EM Machine Power Levels

[Coil_Smoke]

This question has been been a bat some where in my belfry for years. I have wondered if any 60's era pinball machines had two levels of power for playfield solenoids. Some of the games I played seemed to speed up as my score increased. I was just a kid "Down The Ocean" on vacation. Those were nickel and dime machines. I often got the impression the the games started off sluggish with weak pop bumpers and sling shots. Were these machines just warming up from their morning exercise? Or did they have circuits that sent more power as play progressed? This effect definitely added to the fun ...C_S

i have worked on em machines of all eras and have never seen any em machines with different levels of power. dirty solenoid sleeves and plungers will be sluggish , once they work a few times they might loosen up a little. giving the look of more powerful. there is no warm up time with em's , the transformer might warm up but that has nothing to do with its power output. warm up time has to do with vaccuum tubes and cathode ray tubes that have cathode heaters inside them.

Thanks 'pinballdaveh' . I thought it was a good idea but I guess those machines were just limbering up. Maybe some old oil where it doesn't belong was warming up during play.

P.S. To PinballDaveh ... I am amazed by the detailed help you give to those that post here@PinBall Nirvana.
