Hi, I have a Jefferson golden hour electric clock, cat. # 580-101. The clock runs well but gains aprox. 5 minutes per day. I removed the burgundy bottom cover hoping to find a fast/slow setting, but none was found. Is there any way of regulating the motor speed or is replacement my best option. Thanks, Matt.

Steve Berger of Timesavers.com has a cheat sheet here Golden Hour

This is a common problem. The glass is set into a drive ring with adhesive. The adhesive breaks down and the glass rolls loose inside the drive ring.
So, now you think "it's loose, it should run slow, right" ?
The inner ring of the drive gear has a larger circumference that the outer glass rim. The glass carries the hands and due to the smaller circumference completes a 360 dg rotation faster that the 1 rph drive ring. Hence a faster clock.
Available parts and the cure are shown in the link above.

The preceding reply is exactly right. To be sure, try to turn the glass lightly with your fingers. it should not turn - if it does, the glass is loose because the glue has failed.
