Question about Philco 80 Jr.
#2

These radios are not such great performers and if you are not in a strong signal area you won't get a lot of volume. Remember that this set is always operating at full gain, and the volume control just attenuates the antenna signal.

Have you tried adjusting the regeneration control on the back panel? You should be able to bring up the gain of the detector to the point where it goes into oscillation, and then back it off to the point of maximum stable gain. If you can't get it to the point where it starts to squeal, then there is something wrong with the detector circuit.

Marginal tubes also make a big difference in this radio, as there just isn't any reserve gain available.
