I have restored 3 of them and they are a lot of work. There is a "modification" to the tone control circuit that was posted several years ago on ARF that is very worthwhile adding. The original circuit provided very little bass boost which that large speaker can really handle. As you will discover, even in the off mode the system is powering a transformer needed to energize the solenoid for "on". I found it safer to leave the unit unplugged when not being used for extended periods.
I will be happy to provide any help I may during your restoration.
