Yup that's the fellas.
They are also off to one side because the input and output wires from the buffers are the last two wires to be soldered in place. See where it says EXT and RIAA. If I put the resistors smack bang in the middle on even length leads if makes reaching those pads with the soldering iron almost impossible. What you can't see in that picture is that the output buffer boards are 60mm above the main pcb and the front edge of them overlaps those pads by about 5mm, so I have to come at them from the camera end.
Everyone loves black chassis screws, yeh but they're a PITA because they are anodized and screw case continuity across all the panel, so I've been flap-wheeling patches on the contact points today to get that lovely low impedance path to the GND socket from any panel on the chassis. Here she is, six crimps away from being PSU complete.
Got any plans for Sunday Jamie? (Could be possible, I'll know tomorrow).

That is some sexy looking circuitry! Solder joints look perfect, what kind of solder are you using? Top drawer work! You’re not charging enough.

Looks fantastic as usual Simon.
Are the US z-foils different to the Charcrofts that Hificollective do?

Keith they're the same part but US sourced.
Alpha, its Chinese jinhu 60/40 cored solder. The joints look good because I drag it down the legs after the first flow, every joint removed of excess solder. It's a pita.

Trimming the Calvin's has been fun, had to drop one side to 4.9ohm to get a nice null and still leave trimming in either direction.
Soak testing now.
