Socimag CD Hi-Fi Chrom - 1990s - EU
These contain BASF Cobalt Doped Chrome Type 2 tape.
Although these aren't pure chrome, they have chrome pigments and are cobalt doped. What this means is that they bias like a TDK SA, so can be used in decks without manual bias controls.
So just crank the levels to about +4db above what your deck is saying, and you'll find these are fantastic sounding cassettes that offer real value for money.
Although the wrapper says 90 Minutes, on testing, we've found these are more like 88 Minutes.
*PLEASE NOTE* - Although brand new, these are not individually wrapped and there may be cosmetic imperfections to the outer case. These are for using, not collecting.
