ajtj, your post reminded me that I still have an old Norelco 400 reel to reel tape recorder that needs repair. Because of some special tapes that I value (not music) I'd like to have it repaired - best recall is that it exhibited microphonics which were not solved by installing new tubes. Can you suggest any way to get it repaired? In its day (50's - 60's), I think it was a pretty good quality machine. TIA Maury
