i guess the leadwires for the to-3 trannies are gone, since the output trannies solders direct to the pcb, very neat change! i am using mjl1302a and mjl3281a output trannies.
btw, gerber files are available at jen's site. the boards are of 2oz copper, plated thru and is quite thicker than ordinary boards!
that's cool indeed, eliminating 12 wires per channel just for the opt trannies. i've checked the board recently and it seems that aside from the new and neat layout, there is no chage from the original ckt.
one cool layout change that Jen could have included is to position the LTP facing each other and then bonded together for thermal tracking, other than that the board is fantastic.
i have those gerbers a loooong time ago...
