I have an rockola 474 and have fixed most of the problems with it,but one remains. When the unit is first started, i add credits by putting coins in,then select my records,the machine is in the home position,the magazine then moves about 1" then stops, pressing the selection again the magizine moves again. If i select a number that reqires the unit to pass home it will always stop on home and stay there. i then select the same record again, it will play all records as long as it does not need to pass the home position. have checked all micro switches,but may still have a flaky one. I do have the manual. thanks in advance for any help this forum can give.
