Love those early transistor radios ! - You should check all the resistors in the circuits
from the volume control and all to the right of it.... Maybe 3 - Ha Ha ! The single
resistor providing less than stable biasing may lead to poor quality sound by leaving
the transistor not quite turned on, and giving you what may actually be a clipping kinda
sound because it's not turned on until biasing level sound arrives at the transistor...
Poor quality speech is kind of a clue there..... Transistor turns on and off
giving a choppy voice, not a varying level amplification if it were biased on
all the time.....
R11 R13 R14 R15 R16 ?? Too Small to see clearly right now.... Amp supply & biasing.
If they check out, then I guess you'll have to check the transistors....
Could have something open.....
It would be interesting to follow a sine wave through the circuit to see what is going on....
