A little progress, but hopefully more to show for my efforts tomorrow SMPS fixed in place, all the regs changed, spades removed and CCC links in place to solder to for the speaker outputs. IDC sockets removed for the input wires to be soldered directly into the PCB and the back panel is modded to accept the binding posts and WBT sockets: Aiming for it to be functional this week (before Friday)

Nearly there: The output wire to the speaker binding posts is 1mm² solid core CCC, with 24awg stranded CCC from the inputs to the buffer. Three wires due to being wired in pseudo-balanced config, as recommended by BP. Would have been better if I had some shielded CC, but I haven't. All that's left to do is make the ribbon cable, assemble the case fully, and then power it up. Opamps are OPA1656 btw. Chart for solid core current carrying capability: Opamps in situ:

Yeah, nice looking build that is. Love the orange braid on the cables. Good aren't they, the Purifi amps. Borrowed with a view to purchase?
