help with a rockola 490

Hello, I have a rockola 490 that will only scan and play the 200 side of the records. if i select a 100 number it scans through the 200's still and eventually stop. Does anyone know where I can try tracking down the problem? I have replaced both relays, the latch relay and the reverse relay.


Thanks Chuck

Part to check I had this happen also once. the 478 and up are all about thie same. LKook for a switch inside the box. This switch tell it a sode or b side. If it gets stuck it will only play b side.

This switch should be around the front of the box ad mine is blue looking there is a var that pushes it. I gave mine a shot of oil and it works find.

I have the service info for the 578 but not to sure where the switch is on the 490. If you want me to scan a photo of the switch to give a ideal where it might be let me know.

The relay's do not have much of a problem as the switch getting stuck.
