Hi, my name is Chuck. I have been involved with electronics and recording for most of my 66 years; my first recorder was a 1949 Eicor Model 1000 my father gave to me at age 6. I am an electronics engineer by trade. I'm about to start a refurbishment of a 1970's-vintage Sony TC-366 open-reel tape deck. I found a link to this site while researching quality replacement parts.
