Forgot another point: since most table radios were made pinching pennies, they didn't put in large audio coupling capacitors since the speakers couldn't produce much low frequency response anyway. But you can try replacing C14 and C16 with larger caps. The larger the caps, the more lower frequencies the audio section can produce, with highs remaining the same. I'd try .047 mfd. and see how it works. If that's too much bass for the speaker to handle without distorting, try smaller. This plus the tone cap previously discussed should help.
