Hello fellow sound equipment hobbyists! I developed an interest in collecting older sound equipment roughly a decade ago and have recently found this website in my search to become better educated in servicing these older machines. My first ever portable cassette player was a Realistic SCR-51 I found at a flea market with the original box for a few dollars when I was 15 years old. My grandfather graduated from Chico State Collage in California way back in 1973 with a degree in journalism; for the 38 years he was a writer, his weapon of choice for interviews quickly became a Walkman WM-R2. When I first expressed an interest in older sound equipment, he told me nothing comes closer in quality than a well-built Sony, and from then on I was hooked. I've gotten into the habit of replacing the belts whenever I buy a new machine, but recently I've taken a chance on some damaged goods online and I'm looking to gain some knowledge on how to save them myself!
