OK, gang, it is time to tap into the lists' wisdom. I'm working on an Amberola 30. The hook came unsoldered and the reproducer needed a rebuild. Those two easy repairs (the spring was in the case)completed, I tested the phonograph and found that the speed is a bit erratic. It will sound nice, then slow just a bit then return to speed for a while only to slow again. The carriage moves easily and the horn bobbles and rotates as it should. The governor is lubricated and the pad has been oiled. There is no evidence of crud or damage to the governor disk. There were a few teeth on the large hear that had a bit of damage but a bit of judicious filing has cured the noise the damage created, and besides, the speed variation is more random than the cycle of the gear noise. I'm thinking that the mainspring may need to be removed, cleaned and re-lubricated but I thought I might see if there is anything else I missed before tearing it apart.
Thanks, Ron L
