Hi guys!
I already know that it's very difficult, but I try to ask you for help.
The question is the fllowing: can you indentify the IC 1 in the scheme of the picture below?
The IC in question is the triangle with 5 pins: I can read just TDA, the numbers seem to be "2030"...what do you think about the numbers? could this IC be a TDA2030 ?
The only things about this amplifier that I know are the following:
Fuses: Primary: T0 3 A
Semiconductor configuration: 2 IC, 2 transistors 8 diodes.
Output power: 2 x 20 W music
Frequency range: 80 - 18000 Hz (- 6dB)
Output: 2 x speaker 4 ohms
I don't know if these informations could help you to identify that IC.
Furthermore, I've another doubt about the fact that IC could be the TDA2030: the amplifier is from the 1977 or 1978...but in those years the TDA2030 did not exist...or am I wrong?
Thank you very much for your patience and for your support
Best regards
