I have a Sansui A-510 Integrated Amplifier from the '80s. It uses a STK4843 dual op-amp that has failed. There are separate boards in the enclosure for the input selector, volume, tone control, power-amp, etc..., so I am considering just replacing the original power-amp board with a new one.
I have a bunch of LM3886 chips laying around, however I am not sure if it is safe to use them with the 27-0-27 transformer in the Sansui. According to this webpage, a 28V power supply will give an output of 38W * 2 = 76W, which is more than double the original 30W of the Sansui, thus I am unsure if the transformer can handle the extra power output.
I have attached some pictures of the transformer. Please advise if it is sufficient to power two LM3886s.
