Columbia Record Changer/AM-FM Console

[bigaudioal]

So a friend gave me this Columbia record changer - AM/FM player for free. Record changer appears to be a Voice of Music. Part numbers (like idler) underneath start with "VM." Has a "GI" motor. The chassis is a combined amp/am-fm tuner chassis. Back of cabinet says Columbia Model 7001. Tuner/amp chassis says Model T136-2, Serial 067608, Insp. 4PS 33.

Can someone help me find the schematic. Have not been able to track it down. Searched SAMS and no Columbia Model 7001 or T136-2. These are the only models number markings on player/chassis. What am I missing here?

Is this one of those brands that was made by someone else, like "Sears" or something like that? Know nothing about Columbia, but thought they made their own stuff. Should I be looking for another brand for the chassis model number or cabinet model number?

Thx.
