This what's left of the PCB.
Notice the old Philips NE5532 in the opamp socket for now
I will swap it for something better later if it doesn't perform better than the more modern 5532's I've heard.

I've since taking that pic de-soldered the screw-terminal and soldered in wires for connecting with HP-jack.

Perfboarded LT1083 dual rail Vregs, 4.7uF input caps and the very exclusive chassis (former ATX PSU).

Got this headamp too powered on today.

Offset stays within the -8mV to +8mV range on both channels.
