RAKS SP-1S - 1996 - EU - 2 PACK
Raks are probably the biggest cassette manufacturer you've never heard of.
Like SKC, you're more likely to find cassettes they made for "bigger" brands than ones they put their own name on.
Closely tied to BASF, they produced some fantastic cassettes.
This TOTL ferric is from RAKS' last ever production and to my ears is as good as an AD.
Very hard to find, grab one while you can.
