I'm not sure if these are standard tapes but I am assuming so. Yeah I recorded at a high volume while avoiding clipping, i will try on a higher rate again just to see. No equalizer settings or anything either.

This is a deck I recently picked up that successfully dumped quite a few Fujitsu FM-7 tapes I had previously had issues with on two other decks with so I think it should be okay hopefully. Tapes are for sure are a difficult media to preserve though in my experience.
