Newbie question here. My Sony TC-388-4 has a "Tape Select" switch that toggles either "Normal" or "Special". I assume that the "Special" position is for use with tape that has a specific amount of oxide-coating. Question is exactly how much oxide-coating would be appropriate for use in the "Special" switch position? For example, Quantegy 456 tape has 500u oxide-coating, 499 tape has 600u, and GP9 tape has 700u. Am I correct to assume that the "Special" switch position is suitable for each of these tapes?
Many thanks.
Many thanks.
