Rob H. (Handcrafted Tone) has a simple 312 layout with phantom power on board. Output transformer off board.
Project page is here.
The only thing I can't figure out is the values for C5, C6, and C7 which are not in the original API312 schematic.
Also, I can't figure out what R4 is for, and wonder if it should be left off. (Again, not in original schematic.)
Same with C7 - should I just leave it off? (It's a cap before the output - not in original - I assume not needed since I'll be using an output transformer.)
