thanks! I think I will send it to Audio Classics for the Modafferi Mod.
MR71 Tube Tuner alignment
Hi, I have MR71 for 10 years and needs alignment (left channel sometimes is not coming up esp. when cold). I prefer not to ship out of state, so anyone know in or near Chicago area a shop I can go to? If not, I like to know which one in the continental USA can do a good job on this alignment check, based on your experience. Thanks!
