Aiwa AD-F780

Not much is documented about the Aiwa AD-F780 beyond one period test report. Stereo Review (January 1989, p.67) ran a full review of this cassette deck, and that report is nearly all there is.

The review's measurements show frequency response within +0.5/-2.5 dB out to 18,000 Hz on two conventional tapes, and out to 20,000 Hz on metal tape. The reviewer called that very good for any cassette deck. The deck ran slightly fast at +0.87 percent, an error the reviewer could not hear in practice.

The same report describes light-touch solenoid transport switching and a color-coded bias guide for various tape brands on the top front edge. Bias adjustments are made by ear, using low-level FM interstation hiss as a reference. Slide switches handled Dolby B, Dolby C, or no noise reduction, memory stop/repeat, and external timer operation. Pushbuttons covered tape/monitor. One feature, whose intended purpose the reviewer couldn't test, hid the cassette's label completely and made the tape slightly harder to access.

No production years, original price, or further details appear in the sources on hand.
