Transferring music from R-T-Reel tapes reminds me of some problems
I had MANY years ago. I had recorded dozens of RTRs off of AFN while
stationed in Germany in the mid 50s...

I thought the RTRs had been stored as reasonably well as could be expected, in the original cartons but not completely sealed to
keep air out... They had been in storage for over 25 years.

They had deterioriated more than I expected.. As the tape passed
between the Pinch Roller and Capstan, the Oxide coating peeled off
in the floor and the Mylar [now clean and clear] continued to wind
up on the take up reel.

Happily tho, I managed to recover much of the treasured programs..
