API 550A mod to 550M??
« on: April 24, 2006, 03:01:24 PM »
Hello

Im considering converting a pair of 550As to M's for mastering.  I guess what I really need is a 500A schematic.  But I also wonder if anyone has done this mod and know what is involved to change the gain steps to .5dB?

thanks,
mike p
