Yamaha m406 EQ and phantom mod?

[analogggman]

Does anyone have details and/or schematic on the m406 EQ modification? From what I'm reading the phantom mod looks pretty simple, you just split off the phantom, which appears to be coming in right after the XLR input, and put it on 4pdt on on switch.

Here is the m406 service manual. Curious myself about the EQ mod.

Only a few parts in the EQ. Try swapping out different cap values in the EQ section with a frequency analyzer as a starting point.
