Here we have Rowe TI-1 that has a tube amplifier and a mixture of electromechanical and early transistor technology. These jukeboxes have a lot of lubrication issues and adjustments to keep up with but in general really do keep on working like WWII Battleships! The tubes checked out, the button switches and main mechanism did need a lot of cleaning, oil and grease. The relays needed to be cleaned as well. Fixed the "Record Playing" indicator. Made new grommets for the turntable motor. Adjusted the tone arm limits. Lots of little things addressed. All typical of a machine this old.
