Clarification (no pun) is needed on the clarifier pins:
The blue wire is the source 8V, goes to F1 on J9
The white wire, F2 on J9, in any mode is 4.92V to 8.73V
The black wire, FG on J9, in any mode is 4.92V to 5.96V
They are all plugged into connectors on the main board or clarifier board.
Of those, the one that is 4.92 - 5.96 V is the grounded leg of the clarifier, blk wire, according to the schematic for the 959 (same board).
The white wire or F2 has a range of 4.92 to 8.74 one end to the other.
Sorry for the double use of white wire. Was up at 2:30am after not much sleep playing with this thing. I feel like the Scarecrow sometimes.

PLL alignment for AM at TP3 is 16.27000, USB is 16.27250, LSB is 16.26751. L20, 21, 22 respectively. L22 was/is very touchy to get set.

After setting those parameters, receive at USB 27.3840 to get clear audio from a radio tx at 27.385, and LSB 27.3847 to get understandable audio. Then when switching from mode to mode, the LSB at TP3 goes to 16.26738. It doesn't seem to hold it's setting. Now after another aligning on LSB, switch the mode to AM, USB, back to Am and back again to LSB. Now LSB is at 16.26762 without touching the pots.

I'm wondering if the L22 needs to be replaced, but that wouldn't explain the basically same issue with USB. Now I left the LSB at 16.26754, best I could get, I keyed the other radio and the TP3 reading went to 16.26743...without moving anything on the radio.

I thought for a moment I had a revelation as TP3 post was a cold solder joint. I fixed it but no change.

Here is the schematic and service manual I'm working from.

R115 on this board is just below X1. There is an R113 in the area you state. One side is 9V RX, keyed 0.065V...other side 8.8V RX keyed 0.065V.

I learn from everything you say HA. Just the steps you outline are helping me to find my way around so to speak.

I spent a lot of my day cleaning my desk area as somehow the shorting bar got lost. And after cleaning everything up, which really needed it, I still didn't find the little board. I checked the wash and my jammy pockets, everything i could think of...then I happen to look at my soldering iron holder, and there it was nestled in the back of the opening. Things just have to be difficult for me.

Thanks much HA, as always. Some of what I said might not make sense, but I try my best.
