Adam, That looks like an SK77, probably the most desirable model of 1963. I have two of this era, one has 11 speakers and a 15" woof like yours and the other has 5 with a 12"woof. Both have three sets of 6V6 PP and are waiting to be recapped.
My experiences with V-M changers is in a thread here.

In the last year, Ive worked on 16+ record changers, half those were the V-M changers installed 1960s Zenith, Motorola and Philco consoles. There were slight differences but all had similar issues and it took testing-tweaking, repeated disassembly and lube, etc.
I found that once I loosened, cleaned-lubed and then repeatedly operated every part no matter how clueless I was to its function ; motor, pulley, linkage, motor mounts, sliding bar, trip slider, spindle actuator and tone arm adjustments, they were reliable automatic changers once again and worked as designed. If I skipped any step, I always had to go back and do it.
