Looks like that stereo was built by Sylvania in Batavia NY, so it is US made. I once had a Sylvania colorTV built there.

Both Sylvania and the Philco consumer brand were owned by General Telephone and Electronics (GTE) in the 1970's, so it makes sense that Philco products were made at the same factory.

Visited Batavia years ago and found the old Sylvania plant. Building is still there with a different occupant. Locals I spoke to still remember working for Sylvania, building TV sets in the 1960's and 70's.
