This tape recorder still works well. I have over 35 7-inch reels of music I recorded in the early 1970's. I recorded them at 7 3/4 ips, so each reel will hold about 3 hours of recordings. The music includes rock, folk, bluegrass, jazz, and classical. The tapes are still good. They have not exhibited any feedthrough from layer to layer, nor have they become brittle.
