The Mission 778X is based around the design of the Quad Vena II and Leak Stereo 130 which both use the LM3886 as far as I know. Looking at internal pics I can see 6 forward pins on those two but the 778X has 8 forward pins so maybe a TDA7293? Specifications are similar for all the amps and are made in the same IAG factory. I assume when the 778X was designed, the LM3886 supply issues came into play.
I can't see enough through the vent holes and as it's new I do not want to remove the cover as well I do not have a Torx bit small enough.
