good advice and a fantastic amp designed and built by a true audio engineering genius and music lover Roger Modjeski.
great advice on swapping tubes. RAM tubes is the place to go, Roger was also an innovator on computer testing of tubes, matching / grading. His designs feature thousands of hours of operating life. I have his breakthrough RM-9 but you have an incredible amp in the RM-10.
make sure your input cables are not creating the scratch you hear, tight clean connections. There is factory help and tube sales for your amp and a cadre of techs at former MR dealers to help also.
reach out if needed.
finally, the RM-10 is highly desirable, so if it doesn’t work for you, easy resale.
