Default how about 4780 instead?

Begs for multiple paralleled lm4780..
Balancing the things I must do, with the things I'd like to do...This is a skill (or a luxury) amongst many that I do not possess.

The 3886 with a ClassA sinking device will run into overheating problems.
Using the dual chip 4780 in that ClassA format will making the overheating problems even worse.

Yes, an SOA issue most likely. Interesting concept. BTW I was apps support for the 1875, 675, 391, LM12 back in the day. Can hardly believe they are still being used and discussed.
