I'm four years into my archiving project. So far, I've burned up six R/R machines. I finally had a ReVox custom made for my purposes. My suggestion, if you're serious about working with R/R recorders, is to locate a GOOD repair shop. They're hard to find, but there are out there.

I'm in the Seattle area. If anyone wants a recomendation for an excellant repair shop, PM me. bob(deckman)nelson
