Hey All, I just wanted to update you briefly.
I've got the radio working great, and I've replaced the photo sensor and rubber gaskets on the beam of light
pick up. The last piece of the puzzle is a good phono motor which I placed an add in the 'wanted' forum for.
I bought a 78 rpm geared AC motor which works but the gears are a little loud and the motor speed is a bit variable
so it makes the sound 'wobble'. I'm desperate for a direct drive motor that will work for me but I've also contemplated trying
to build a pulley and belt system underneath to drive it with a modern turntable motor. Does anyone know if i'd just experience the same 'wobbly sound' issue? I guess the best way to describe it is the speed of the motor increases or decreases randomly, not by a huge amount, but enough for you to hear the difference in pitch.
If anyone has any suggestions or maybe a motor available, please let me know.
I've contacted west tech but I don't think they can help me.
Any suggestions would help.
