Hi all,
So I have a goal to make a 312 with (choose at install) trafo or 1646 output. Here is the schemo I drew up for this.. based on the original with various other things from hints from different people/schematics here and elsewhere.
Before anyone asks, the 2caps+resistor in parallel is how I've heard API are doing things now (haven't seen any new API stuff open so can't say for sure), but is also the way Eisen audio has their kit set up. I tried it out and it worked well for me on a couple of other boards. The 1646 is straight off the datasheet... all this unless I made a mistake... like is my pot turned right side up? Are the switches correct? Anything else that stands out?
Anyway, I tried this with a DRV134 chip in an SSL9k balancing board and it worked well (even with shabby components/wiring, so hopefully it will sound spectacular when done properly).. Tried it with a melcor and a Hardy 990, both sounded good.
I realize this project is a bit been there, done that, but if you have any comments, I'd really appreciate it. Thanks!
