I had a similar tracking issue in a KV-20FV12, caused by a soft CRT. The cure would be to raise the CRT heater voltage a bit. Not being a Sony specialist, I didn't know if there's a resistor in series with the CRT heaters (as there is in many brands). It would be a small value, like 2 - 3 ohms, and would be on the neck board. So I asked the Sony gurus on here, and sure enough there is. So I jumpered that resistor an lo, the Jug came right up and looks great to this day. If yours has that resistor, try jumping it temporarily and see if the tracking improves.
