Everything was going fantastic with the final alignment until 12m then nothing. Only 0.2 indicated no matter how I adjust C44 or C46. Quick search of the archives and a look at the schematics points to soldering, C44, C45, C46, soldering, K6, VCO or soldering as potential causes. Pulled off the bottom plate, got out the magnifying headgear and scrutinized every joint. Beautiful joints, nice smooth fillets on both sides, even got out the alcohol and cleaned 'em up a bit more. Checked TP1 at 24890 and got 19975.75 so the VCO is fine. Set to 24900, hit TUNE, still 0.2, tweak C44 a bit then BAM 4.6, a few more iterations between C46, C44 and she's peaked at 2.1 as requested by the power setting. So hummmm, could the wiper on C44 have been dirty or something? I know I twisted both the full range when it first failed. Interesting but happy ending. Hope this tid-bit may prove useful to someone else.
