hi! i have a denon dp-33f (fully automatic TT, used to). The auto function on it is NOT working tho... i can still play records on it but have to put and take the arm off manually. the LOCATE/START knob, LIFT and STOP buttons don't work. i'm pretty sure the control motors for the tone arm works as proven by connecting them to 4.5 volts... any input is highly appreciated!
