Well, here's what I wound up with for the drive transistors:
Group 1
2SA1358Y: 148, 148, 150, 153; spread 5, average 149.75
2SC3421Y: 148, 148, 148, 149; spread 1, average 148.25
Group 2
2SA1358O: 128, 129, 129, 131: spread 3, average 129.25
2SC3421Y: 128, 130, 132, 133: spread 5, average 130.75
It's not perfect, but pretty good. Started with 20 of each.
