That looks like a great console. This is nothing like taking the back off to confirm what a fine set of matched components you got
The platter mat on that record changer looks identical to a 1963 Zenith changer I'm working on now. The control levers and tone arm are nothing like it though. Very interesting.
The 7868 was not used often and I only recall working on a Fisher 400 that used them in push-pull.
