Review on Synthesizer CASIO SA-77 black / gray by Mateusz Roczon ᠌

For the initial education of children, more is not needed. The power supply (adapter) can be purchased at any radio store. The adapter needs 9 volts and 1 ampere, it costs about 500r. It is better to buy a universal one with which you can switch the output voltage, something like the Robiton PC1000 or SN1000. The Casio SA-76/77 synthesizers are exactly the same except for one colored button that switches from piano to organ (SA-76) / reed organ (SA-77) and the models differ slightly in the instruments printed on the body. Not all tools are printed on the case. In all models, the brains are the same and the tools are programmed the same, the difference is only in the few inscriptions placed on the case. Model SA-78 and SA-76 differ only in color. In short, you can take any of the three models, they only differ in color and one button, which is generally not needed.
