There doesn't seem to be any consistency in TX4 boards and what truly is Phat/Non-Phat and what is needed to reverse a Phat Mod from all the pics/info I'm finding. Here is the info for supposedly reversing a Phat Mod:
"To reverse "Fat Mod" you’ve to add 4 caps and 4 resistors and change 2 resistors.
1) Add 4 resistors:
R9 :120 KOhm
R44 : 33 KOhm
R45 : 330 KOhm
R46 : 82 KOhm
2) Add 4 disc. caps:
C5, C6 & C12 : 0.001 µF
C22 : 47 pF
3) Change these 2 resistors near the center of the board and labelled MID & BASS. Replace them with:
R33 (MID) : 1 MOhm
R34 (BASS) : 10 Kohm"
Seems straight forward enough. Problem is, here's a pic of one that's supposed to be a non-Phat mod:

But then I glance through it, see no C6, no R9, etc. So I think "maybe it's really a Phat Mod." Then I run across this, which is also supposed to be a non-Phat mod:

BUT, this one is missing R46 (though the other has it), R9, it has C6 (where as the other one doesn't have it), etc. So what gives?
Neither one, both supposedly non-Phat models, match up with the instructions above for removing a Phat mod. So for anyone technical, are either of those or neither those a non-Phat mod? Are those instructions above right to remove a Phat Mod?
Hoping someone can share some insight, because I can't find any consistency. There's 2 TX4 boards that are supposedly non-Phat, and they don't match each other, and neither one matches the instructions for Phat Mod removal.
Anyone here with factory non-Phat Mod v2 care to post a pic of their TX4 for comparison? Hoping someone in the know can shed some light.
