The following problem with my Wurlitzer 2300S: when the selection buttons
are pushed, they both block. Nothing else happens, there is no record
selected. The two resistors on the selectionboard get very hot.

When I pull the selection-pins inside the jukebox, it plays all the selected
records.
Anyone out there who can help?
Is there a site I can find more info?
Perhaps also a manual on how to repair this jukebox?
I am grateful for any suggestions.
