Going through a phase...

You can't go by the printed schematic, check the silk screen on the PCB.

The c84 silkscreen reads 1.3, so I'll be sure to reverse the phase switches until I solder some crossed wires to replace the zero ohm resistors.

The C84 schematics for the kits I built was 1.3, so I am guessing the phase is reversed. The existing zero ohm resistors have been trimmed and can't be crossed. I assume I can just solder in crossed insulated jumper cables to make the phase right, and don't have to use zero ohm resistors. Correct? I would like the phase switch to report the correct setting. BTW, tonight I use the mic pres for the first time. Recording a jazz band on location, 24 tracks, two of which will use C84s. I'll make sure the phase switch is reversed for this gig.

I confirmed the older version C84s have backwards phase compared to my new N72s by looking at the waveforms in ProTools. I soldered cross connections on L1 and L2 using some leftover wire, and re-checked the phase and now all is in sync. The phase switches can now all point the same way!

Thanks Tim! Great kits.
