McIntosh C220 tube question
Has anyone tried any tube rolling with this preamp? According to the manual, tubes should only be replaced by an authorized technician. I've changed tubes in my previous preamps with no problem. Is there something that makes the C220 more difficult? If you have done some tube rolling, which tubes did you experiment with?
