Hello Radiofriends, please who know the difference between the "A" version ( TBA570A ) and the normal type TBA570? On the original 1977 Philips IC's handbook ( page 66 ) there is only the sentence : "In its standard applications, the TBA570A can replace the TBA570" Thanks ! |

They did some minor changes in the AF part of the circuit to make it more stable and powerful (driver). Details can be seen in the circuit diagrams; I just uploaded the slightly different diagram of the TBA570A, see pins 10...13 area. Hope that helps. G.S. |
