    Do the Yamaha CR-1020 and 2020 have the same output amps?

    Hi all, I feel kind of silly asking this but where comparing pictures the amp output assemblies and parts look identical. I have not been able to compare parts lists for these two and thought I would ask since a lot of parts are interchangeable on these.
