I'm in the process of building just such a beast 🙂 Not finished yet, might be a couple of weeks before I test it. I'll let you guys now how it goes.
I have a lovely 15v bipolar supply to go with these.
are you using 4 boards for the balanced build?
are you using 4 boards for the balanced build?
Is the gain 2 with the values in BOM?
If I go balanced will gain be 4 then?
Edit: The BOM says R1-R6= 10R that cant be right,?The schema says 2K.R4,R5.
And R1 is 21R.?

Gain is 2 in the BOM so going balanced will double that.
The BOM and schematic I have says 10R on R1-R6 and thats what I built.
having ordered some boards from the group buy, i have looked through the parts bin to see what i can scavenge.
I have a fair few bc549b and bc556b. can these be used as the Q's without other changes?

Yes, I did. I didnt experiment outside Russ Whites instructions, but Im sure there is room for it.

Look at post #257, I've got a HD-650.
A little bit more gain will be magnificent...😉
any views on the bc556 and bc549? hoping to get an order in for the rest of the parts sometime today.

They will work, but since BC547C & BC557C are widely available and dirt chip, I see no point using other then specified ones.
