Well, that is an odd one, I used to have a schematic from James with a hand written adjustment for both the free standing one and the standard one, but can't find them any longer, just my own notes on what was ordered for the previous GB. This must be because 2.5uF caps aren't a thing (at least not at Jantzen). The short answer is I have no idea after all this time how the adjusted values came about now, maybe James can remember? Maybe the recently posted schematic was an earlier version? The standard version has a 2.7uF instead of the 2.5uF in the recently posted schematic too. Same story with that. Everyone in the previous GB had the values I supplied this time too so there must have been some discussion at that time, although as I said I cannot recall now. I only noticed myself on Friday when I was testing some of the crossovers.
