No kidding. Got an 85lb powered sub, no one local can install new amp board. Friend inherited a nice TEAC R2R that needed attention -- no luck. In my childhood we had three independent radio repair shops. Long gone. Radio Shack had the last gearhead, young kid; they closed 10 years ago. Canada was a bastion of FM connoisseurship for obvious reasons. Now it may be Eastern Europe.
