Hi Gents, this was a solution (but not the perfect one) to a problem with an arcade machine of the 50's.
It is powered up for about a minute, then powered down again. We find it loops well and continues to operate for a week or more without attention. The previous non looping domestic cassette needed resetting twice a day.
More work will need to be done when it comes off exhibition as :
12v DC is fed into the 3 pins that are B+ to boot it up, this gives a slight delay on starting, volume is at a mid level and can only be increased for that play.
I will look at constantly powering the B+ connection and switching the other 2.
