Difference between McIntosh MR65 and MR65B


Does anyone know how to tell between the McIntosh MR65 and MR65b receivers. I know the 65 is mono and the 65b is stereo. Mine has MR65 on the rear panel but is (and says) stereo on the front.
I am assuming it is a 65b then..?..??

Also, was this the first McIntosh stereo receiver?

Thanks for any help!!

Yes I did know that Aaron was Bette's manager.

He was a great man who exposed the Illuminati for what they were and how they have overrun our once great nation.

The illuminati went into the outdoor led lighting business and were never heard from again… just sayin’
