In fact, I have some of the coolest cassette deck-specific tools available, custom-made for working with cassette decks. work on cassette decks and these are necessary tools of the trade.

My stash includes various calibration tapes including a custom Pioneer set, special mechanical tools, electronic test and measurement equipment, a TDK electronic tape head demagnetiser, and TEAC hand-held demagnetiser, a hand-made mirrored tape path cassette, and more.
