Wow. I just noticed this. A brilliant find.
I have seen the original amplifier on ebay. And the speaker I believe was probably the model 106 which pops up now and then.
The challenge will be finding the original changer. I believe was the second Victor changer like the one in a Victor 10-35 but with an electrical horseshoe pickup. I believe it would have looked like this on on You tube but they are so rare i have never seen one.
