Step 2Turntable Alternative
If you don't have a 78rpm turntable or would like something more compact, a dc brushmotor with a built-in gearbox is a good alternative.
Use a variable dc powersupply to adjust the voltage that drives it to change how fast it spins.
The speed won't be perfectly steady but it will be good enough.
Most dc powersupplies have a voltage adjustment somewhere in their guts if you look around. Don't get electrocuted.
This motor is a 24 volt Pittman GM8713G883 with a 31:1 gear reduction. I'm happy with it.
