i have 4 turntables and want to connect these so that when 1 LP record has played then the next turntable cuts in. Answered

this is to overcome the need to flip to the other side [as LPs were short on playing time]. i have little skills in this area so need simple instructions/directions. david@davidturnbull.net

I don't think there is a really simple way.

Most turn tables have a switch on the tone arm so that at the end of the record the power is turned off perhaps you can use this.

Really without seeing what you have it isn't easy to design a solution other than a complicated universal approach that you may not be able to make.

e.g. sensing the tone arm position, using a microprocessor or electronics to switch relays to put the next turntable on etc.

I would go with Steve and transfer to digital media and string the files together with Audacity or similar.

I concur, it was my first thought.

Do you have to use LPs, could you simulate it by recording the LPS to modern media, and then pretending the tables are playing ?

I'm an Electronics Engineer old enough to know what you are talking about.

I would use a small 1/4" dia NIB magnet glued on the back of the
pickup arm and have it trigger a small relay using a reed_switch
or a hall_sensor which could power the next turn table.

If you want the table already spinning at 331/3 rpm
and to start with by placing the pickup arm on the record
you will need to add a small servo-motor to do this action.

I don't know of a simpler way to do this. Unless we have a Rube Goldberg
answering questions with a mechanical sequence
