I've gotten to that point where I realize I only understand enough to know that this is not something I'm going to be able to figure out on my own - I've spent the last few weeks digging through information and reading.
I would like to try regulated power on the SuperSymmetry chip-amp I'm working up. I'm using two LM4780 chips per channel which should have a 10-15A capable supply. These will be monoblocks.
Worst case, I'll build it without regulation.
However, I would very much like to try a regulated supply.
The LM338 datasheet has a couple outlined, but they use obsolete chips in the circuit or are not recommended for more than 25V at best (though, I am not entirely clear where that voltage limit is being derived).
One of the things that has crossed my mind would be to supply each chip with its own regulator and not have a common power source (though I would still use one transformer and one rectifier bridge, and thus one capacitor bank behind the regulators). But I don't know if this is a good idea.
Other ideas and options are welcome.
Thanks!
