Wow!! Sweet finds!!
Is the wood cabinet with the doors the re-purposed cabinet for the Heath?
Someone( probably the father who was a service tech) appreciated the significance of the Fada set, given they re-tubed it in 1979! That would not have been a common thing to do.
I had a GE 16 inch BW set from ther late 50's that I re-tubed about that time for $25
