BASF Chrome Extra II -1991 - 1st. Edition - DE WARNING! These are "pure chrome" Type II tapes. If your deck is calibrated for ferro‑cobalt Type II (e.g., TDK SA), you’ll need to re-calibrate for proper results.Most tapes marked ‘Chrome POSITION’ aren’t true chrome. DuPont created and patented real chromium dioxide, and many brands avoided licensing it, opting for cobalt‑doped ferric instead.Pure chrome can behave unpredictably in decks without bias or level adjustment, especially Japanese models tuned for tapes like TDK SA, Sony UX, Denon HD or Fuji FR-II...Because of their specialized behaviour, these tapes are best suited to users familiar with true chrome characteristics. Please purchase only if you’re confident working with real chrome formulations, as returns aren’t accepted. This is one of the last "pure chromes" BASF made. The shell, looks like a cheapo clear one, but this is a very heavy, well made, interesting shell with distinctive ridges. All in all, one of the last truly great 100% BASF cassettes.Note 1: 100 Minutes: 1991: DE: SOLD. About BASF: Founded in 1865, BASF became one of the true architects of cassette technology. Their deep expertise in magnetic chemistry shaped everything from early ferric formulations to the reference‑grade chromium dioxide tapes that defined real Type II performance. BASF shells were engineered with precision, their oxide coatings were remarkably consistent, and their true‑chrome behaviour remains instantly recognizable to anyone who’s ever dialed in a deck properly.Even after the BASF name left consumer media, their formulations lived on through EMTEC and later Recording The Masters, keeping the BASF lineage active in modern tape production. For collectors and recording buffs, BASF’s influence is still very much alive — a technical legacy that continues to matter every time one of their tapes hits the heads. BASF Chrome Extra II - 1991 - EU - Tape Made in Germany.
