Hello All!

I'm new to the board but have been an audio nut for 45 years. I recently purchased a storage unit with a bunch of nice gear including what appears to be an 806A but I'm unsure that it is legit because the magnet structure and diaphragm are different than any photos that I can find on the net.

Any chance anyone knows what I have?
