Receiver AKAI of the mythical AA series, has been recently revised and adjusted. I have tested this amp playing for many hours without pause with high-end speakers and the sound is clean and bright with powerful bass and brilliant highs as expected. Some letters are erased by use and one of the lamps, the one with the FM signal indicator does not turn on, otherwise everything goes perfectly, the three speaker outputs sound perfectly at full power. There is some minimal cosmetic damage shown in the photos, and some erased letters, nothing that is not typical of the passage of time, it is 40 years old.
