Hello,
I finally brought out the good ol Slant Face Roadtalker SSB radio. I honestly forgot when i did the clarifier mod to it. (Must have been a few years ago.). I did open it back up and seen that I already moved the wires and soldered them to the places they needed to go.
***Purple wire is connected on the R303 on the side where it needs to be in with D301 (banded)
***Green wire connected to where the red wire is (8V source) The black wire coming off the Fine Tune is just going to a nearby ground.
While the radio is on, stations come in great and the Fine Tune knob is basically right in the middle. What I failed to realize, is that when you transmit, it is way off frequency on the other side. It will follow your Fine Tune as you move it and can tune on in so on the 2nd radio here (My Grant XL) is able to hear it find, but then now that puts everyone else while receiving the audio that far off frequency.
Another thing that is happening is that when I leave the radio alone, it will eventually just fall off and go silent. It wont come back until I transmit again and then the receive comes back for just a little bit longer before it goes away. I dont even have to move the clarifier for it to just drop out. On the Clarifier mod, it does say if that happens, then to jumper D301, and then put back the purple wire from where it was removed... The problem? I have NO idea were I even pulled it from lol.
Been too long ago.
Even if I were to restore the wire back and jump D301, is that going to even remedy the issue of the transmit being so far off frequency? Surely there has to be a step to disable the TX adjustments inside like you usually do on other radios? There were the steps that I followed:

Thanks to an awesome youtube video, the correct way to do the clarifier mod was shown, so I went ahead and posted the corrections here. Now Both receive/transmit will be on the same frequency.

Corrected CLARIFIER MODIFICATIONS for ye olde Sears Slant Face SSB:
1)Find the green wire coming off the FINE TUNING control. Follow the wire to the pc board where it connects and unsolder it.
2)Find the RED wire behind the meter display and solder the green wire form before to that location(there is 8VDC there. Don't do the red wire closest to the front, that one is 13V DC!. When in doubt, use a Multimeter to check voltages.)
3)Find the BLACK wire from the FINE TUNING control and unsolder it from the PCB. Find a ground point and solder the black wire to it.
4)Follow the Purple wire, but LEAVE the purple wire alone. This does not need to be moved. Find the one side of resistor R303 in the same area and either desolder one of the legs or clip it from the other side. The area should look something like this:
This mod will give you about 3khz up/down off the "channel".

Hoping some insight on what else needs to be done or even help on the location where that purple wire came from would help too lol. Thank you so much for reading.
