Both amplifiers have original AA-905 face plates and original bottom covers. The feet on the bottom covers are different size and that is one amplifier looks a little taller than the other, which could be remedied by placing a set of the same feet on each of the amplifiers.
I have just chosen to let the new owner decide on what type of feet he or she would prefer. I have not done extensive polishing on the brass but it looks like it could be brought to a shinier level than I polished them.
