Well, it was time to service the machine anyways. I found a mainspring that was ready to break, so I got 3 new main springs, new governor springs, and a straight spindle from George and cleaned/ overhauled/ adjusted.
Now the noise is even worse.

In fact, it's so bad it's interfering with the music. Before fixing everything the noise would diminish greatly with the needle on the record, but not now. In fact
everything I've tried to correct this seems to just make the noise worse! For example, I adjust the position of the governor- it gets worse. I put the governor back where I started- it gets even worse. It almost sounds like a broken governor spring but it's not.
Before, with the motor board up the motor ran *almost* quiet. Now it's noisy with the motor board up, noisier with the motor board closed, and even noisier still with the turntable on. Motor runs strong and the speed is dead even.
Using a listening device, I find the source of the noise to be at the speed regulator side of the governor where the little sleeve it rides in mounts. I can replicate the noise with the turntable when the springs are wound down. Turn the TT and it's knock- knock on the governor.
The drive gear on the spindle LOOKS fine, but could it be worn? Seems to be a lot of slop there.
Incidentally, with the replacement spindle, the side to side play where the spindle comes through the motor plate is barely detectable.
I've never had one like this.
