If there is a large capacitor or battery connected to a pin on the tuner integrated circuit, that's what you'll want to replace. It may be placed after a diode in the line so that the cap or battery supplies power only to the preset memory when power is off. That's how you can probably identify it. Then again, it may be internal to the chip, and if that's the case, you'll have to replace the chip to fix the problem.
