Audio Generator CA-101 ~ 2 resistor values needed

Looking for help in determining two resistor values in this CA-101 audio generator.
This is a 'Madell' brand, although I see this identical CA-101 unit with other brandings
such as Lonwei, Tronon, TAG0101, RAG-101, etc.
I'm looking for a schematic or at least what the values of R41 and R43 are. If no schematic
is available, perhaps a kind-hearted owner of one might be willing to 'pop the hood' on
theirs and report.
In the accompanying picture R41 has been removed from the circuit board.
Both are so charred that the color bands cannot be succesfully read.
Thank you kindly,
