Solder all wire wraps. Time to replace all electrolytics. If still does not work, the tuner requires lab equipment to repair & align. You will have to hire a tech.
As for electroyltics, use CDE 380DX for the main PS filters & if you cannot trace the audio caps, just replace the rest of smaller caps outside of the power supply board with Elna Silmic II. The Elna are pennies each from DigiKey and outperform the expensive Black Gate anyways that are not being manufactured any longer.
I did the op-amp & capacitor upgrade to a Philips 7851 & the receiver sounds way better than anyone with reason will believe- until they hear it.
