I've got a PS that has 60-0-60 volt DC loaded. Not to sure of the amps but it's huge. Can you think of any diy amps that can handle this voltage? The Chip amps seem to like lower voltage.
I never expected this much response. Luv this site and I learn something new every day.
A very good tip on the LM49830. That lead to some other things. The LM4702 also was of interest among others. There was a group buy at one time but it seemed to disappear.
If I read the data sheet correctly it requires two different power supplies, one for the chip amp and one for the mofets. Is this correct? The chip amp really makes these easy to build.
These amps have a lot more power then the LM 3875 which I made need.
