I searched and searched and searched. Everything has been reflowed and looked over. Tried several known working daughter cards. Tried 2 tubes. Tried a different neck board. B+ is 127.8v. Obviously recapped. Adjusted the crap out of every knob.

Is it a bad flyback? Sure seems like it.

 
replacement of C621 is essential now. they're too old. also I would encourage working all adjustment pots with contact cleaner particularly the Black Level on the signal card. they can wear into the surface and break should you ever be left with a black screen and probably no neck glow on a K4600

I always replace C621 when I do a cap kit. I have 4 sets of working daughter cards and they all behave exactly the same.
