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.- SharkBait07

CR 2020 Pre-amp to Power amp connection
I want to know if I fabricate a jumper to connect the pre-amp to the power amp on the back of a CR2020 does it need to be shielded? I know I can use the switch, if I service it, as it is not dependable at the moment, I really just want to know about fabricating a jumper. -
