Thanks will do
,i am thinking of a variable frequency supply to drive the motor .
Also i have 100 watt amplifier for a ceramic cartridge record testing.. it works BTW to reverse a play back to a record you need around 70 watts.... the old vintage type i have doing a sweep test it go's to 8 khz a modern go's over 10 khz i hope once i do a recording to see the limit here
Would be a goal to be able to record narrow band Television i can play back comes down to the bandwidth
On your Question its used a bit by others on record lathes, i tried it on Mk1 lathe as in photos does work messy but yes !
The colour photo was a 36 sec Test recording slower SSTV i found harder on playback ..bit messy as you see manual control of the magnet to slow down the platter and get it sync ..magnet has to be very close to the platter .
