One would not think such ever existed, but this Philco was made in the USA. |

It appears some of these earlier transistor designs were rather void of electrolytic capacitors. The Astor HPN was similar in this regard. It seemed to make them somewhat more reliable than later designs. |

I too like the Philco's elegant design with stable voltage dividers providing 0.1v forward bias for all stages except the audio driver that uses a single 100k resistor to do the same thing. |
