Wurlitzer 3300 solenoid, relay, or transformer?
Hello wiser people than my self,
I'm helping a friend revive a Wurlitzer 3300. We are currently stuck with the solenoid that holds the selection buttons not fully retracting. And the J1 relay buzzing. I'm wondering if both or either of these are are being caused by a bad 24v transformer? Thank you for any direction or suggestions. -George |

If DC then a bridge rectifier diode could be bad, and if AC it is more likely that a connection is poor than the transformer is failing. Check the voltage across the coil when it is energized. Should be around 24 V (AC or DC, can't recall). If it IS that voltage then check for mechanical problems stopping the plunger from going all the way in. Manual first though, always a good idea! I sell them for $35 plus postage...

Wurlitzer 3300 solenoid, relay, or transformer?
Hello John,
I do have the manual. It has helped get me to this point. I will have to do more research on reading the wiring diagrams. Thank you for your help. Do you sell parts if it is the relay or solenoid?
